Edit Step 1 Motorola Moto 360 Teardown  ¶ 

  • Please welcome the Motorola Moto 360 to the grandest teardown stage of 'em all: ours.

  • Tech specs:

    • TI OMAP 3 processor

    • 4 GB internal storage + 512 MB RAM

    • 1.56" backlit LCD display with a resolution of 320 x 290 (205 ppi)

    • Bluetooth 4.0 LE

    • Pedometer + optical heart rate monitor + ambient light sensor

    • Vibrator motor + dual microphones

Edit Step 2  ¶ 

Image 1/2: The backside of the Moto 360 is marked with technical specifications in fun holographic text.

Edit Step 2  ¶ 

  • We at iFixit appreciate fine craftsmanship. The Moto 360 has some of the finest external craftsmanship we've ever seen on a smartwatch, featuring actual stitching and a Horween Leather wristband.

  • The backside of the Moto 360 is marked with technical specifications in fun holographic text.

  • The Moto 360 is built with corrosion-resistant Grade 316L Stainless Steel and is IP67 water resistant.

    • An IP67 rating means it is protected against immersion in up to a meter of water for 30 minutes.

Edit Step 3  ¶ 

Image 1/2: This means that you can use any Qi charger that you might have lying around, as long as you can get the coils to line up correctly.

Edit Step 3  ¶ 

  • The Moto 360 is the first Android Wear smartwatch to ditch physical charging ports in favor of inductive charging.

    • This means that you can use any Qi charger that you might have lying around, as long as you can get the coils to line up correctly.

    • It's been reported to use the official Motorola Moto 360 wireless charger that comes inside the box for best consistency, using 3rd party chargers only in a pinch.

  • The lack of a physical port means that debugging will have to happen over Bluetooth. Thankfully, Google has provided documentation for such a feature.

  • Stay tuned, we'll be diving into the charging dock a bit later.

Edit Step 4  ¶ 

Image 1/2: That said, the included instructions tell us replacing the band, or adjusting a metal band requires "specialized tools" and the skills of a jeweler. We had no trouble with our trusty [product|IF145-020|tweezers|new_window=true].

Edit Step 4  ¶ 

  • Motorola claims that the Moto 360 should fit any standard 22 mm wristband.

    • That said, the included instructions tell us replacing the band, or adjusting a metal band requires "specialized tools" and the skills of a jeweler. We had no trouble with our trusty tweezers.

  • AnandTech reports that "New RF techniques were also used to make custom metal wristbands that don’t interfere with the antennas of the watch itself", implying that third-party metal wristbands may cause interference.

    • Looks like users hoping for a classy metal band will have to wait for the official fall release, or risk spotty connectivity.

Edit Step 5  ¶ 

Image 1/3: Just one more win for our champ, the [[Topic:iOpener|iOpener]].

Edit Step 5  ¶ 

  • The adhesive in the Moto 360 is proving to be a real challenge, so we heat. We heat again. And finally, we heat some more.

    • Just one more win for our champ, the iOpener.

  • The Moto 360 is living up to its IP67 standard. Even getting the plastic rear cover off is a huge pain—hopefully meaning you can rest assured that dust and water are staying out.

  • Even though we were careful when prying with an opening pick to separate the rear cover, we managed to crack the cover right down the middle. Looks like we just lost our IP67 standard.

Edit Step 6  ¶ 

Image 1/2: A PPG is generated by shining light onto your skin and measuring the reflected light, tracking blood flow and therefore your pulse.

Edit Step 6  ¶ 

  • With the rear cover removed, we get our first look at the photoplethysmogram (PPG) heart rate sensor.

    • A PPG is generated by shining light onto your skin and measuring the reflected light, tracking blood flow and therefore your pulse.

  • There are several markings as well:

    • FCC ID: IHDT6QC1

    • Anatel ID: 1510-14-0711

  • Anatel is a Brazilian government telecommunications agency that approves devices for marketing and sale in Brazil.

1 Edit Step 7  ¶ 

Image 1/3: We suspect Motorola has a special tool for this job. For the rest of us, there's the [product|IF145-259|Jimmy|new_window=true].

1 Edit Step 7  ¶ 

  • The Moto 360's innards are sealed in tight. No easy point of entry and a rubber o-ring waterproof this oyster, but make it extra difficult to open.

    • We suspect Motorola has a special tool for this job. For the rest of us, there's the Jimmy.

  • Instead of a pearl, we find a round motherboard squeezed into the inner enclosure. A couple of data cables run to the front panel connecting the two halves.

  • Disconnecting the LCD and digitizer cables frees the halves for more exploration.

Edit Step 8  ¶ 

Image 1/2: The o-ring is essentially a fancy rubber band. But for technical purposes, we will refer to it as a fancy rubber o-ring. After all, [guide|27613|we are professionals|stepid=67527|new_window=true].

Edit Step 8  ¶ 

  • Any good water resistant watch will have some fancy seals. Our Moto 360 is no different, and it keeps water away from its innards with a colorful rubber o-ring.

  • The o-ring is essentially a fancy rubber band. But for technical purposes, we will refer to it as a fancy rubber o-ring. After all, we are professionals.

Edit Step 9  ¶ 

Image 1/3: A brassy semicircular ring surrounds the inner housing, providing a ground connection between the motherboard and outer bezel.

Edit Step 9  ¶ 

  • A bit of prying frees the motherboard assembly from the rear housing.

  • A brassy semicircular ring surrounds the inner housing, providing a ground connection between the motherboard and outer bezel.

  • If you take a close look at the motherboard assembly, you'll notice five spring contact pads that line up with openings through the rear housing—perhaps an access point for programming, testing, or hardware hackers.

    • (Just peel up the FCC sticker under your watch band, without disassembling your Moto 360, to access these pins).

Edit Step 10  ¶ 

Image 1/2: Talk around the water cooler is that the Moto 360 suffers from an [link|http://gizmodo.com/moto-360-hands-on-the-one-weve-been-waiting-for-proba-1630875506|abysmal battery life|new_window=true].

Edit Step 10  ¶ 

  • Motorola has graciously included a pull tab to ease removing the Moto 360's battery. Considering the work it took to get here, it feels like a bit of a joke—sort of like handicap-accessible bathrooms on the second level of a store that has no elevator.

  • Talk around the water cooler is that the Moto 360 suffers from an abysmal battery life.

  • Let's compare its battery capacity with its competitors, the Samsung Gear Live and the LG G Watch:

    • Motorola Moto 360: 3.8 V, 300 mAh battery rated at 1.1 Wh of energy.

    • Samsung Gear Live: 3.8 V, 300 mAh battery rated at 1.14 Wh of energy.

    • LG G Watch: 3.8 V, 400 mAh battery rated at 1.5 Wh of energy.

1 Edit Step 11  ¶ 

Image 1/1: '''Update''': [http://arstechnica.com/gadgets/2014/09/ifixit-cracks-open-the-moto-360-finds-smaller-battery-than-advertised/|Ars got a response from Motorola|new_window=true]: ''"For Moto 360 we only had room for one figure and choose to list the minimal capacity of the battery. We see how this can be confusing and we will look into ways to add the typical capacity as well in the future."''

1 Edit Step 11  ¶ 

  • There's something afoot, because Motorola has marketed the Moto 360 as having a 320 mAh capacity battery, but the battery is clearly marked as 300 mAh.

  • Update: Ars got a response from Motorola: "For Moto 360 we only had room for one figure and choose to list the minimal capacity of the battery. We see how this can be confusing and we will look into ways to add the typical capacity as well in the future."

Edit Step 12  ¶ 

Image 1/2: The Moto 360 is the first Android Wear smartwatch to feature inductive charging. Previous Android Wear smartwatches like the [guide|27038|Samsung Gear Live|new_window=true] and the [guide|27037|LG G Watch|new_window=true] featured metal charging contacts.

Edit Step 12  ¶ 

  • After peeling off a (seemingly nondescript) backing sticker, we find a shiny inductive charging coil.

  • The Moto 360 is the first Android Wear smartwatch to feature inductive charging. Previous Android Wear smartwatches like the Samsung Gear Live and the LG G Watch featured metal charging contacts.

  • Inductive charging works by passing an alternating current through a transmitter coil (charging dock), which creates a magnetic field. This magnetic field then induces a voltage in the receiver coil (pictured here), which charges the battery.

Edit Step 13  ¶ 

Edit Step 13  ¶ 

  • Let's play "Is it Magnetic?". The rules are pretty much self-explanatory.

  • Would you look at that, it's magnetic. We suspect that the charging coil's sticker backing works like a transformer core, made of up ferrous material that "serves to greatly reduce the magnetizing current and confine the flux to a path which closely couples the windings."

    • Tl;DR: we're thinking this sticker improves the inductive charging efficiency.

  • David clears things up for us:

    • "It is most likely a shielding for the main circuit board. When you are focusing a lot of energy through space, you cannot guarantee it will all end up on the receiver coil. Therefore you will need a shield to absorb any stray energy. Just think, if a wire just happens to be the perfect shape to receive energy, it will likely cook the circuit."

Edit Step 14  ¶ 

Image 1/1: Texas Instruments [http://www.ti.com/lsds/ti/dsp/c5000_dsp/overview.page|TMS320C5545|new_window=true] Fixed-Point Digital Signal Processor

Edit Step 14  ¶ 

  • We finally find what's inside the Moto 360's delicious filling—lots of ICs:

    • Texas Instruments TMS320C5545 Fixed-Point Digital Signal Processor

    • Micron Technology MT46H128M32L2KQ-5 IT (labeled as 2SB28 D9QRM) 4 Gb (512 MB) Mobile LPDDR

    • Toshiba THGBMAG5A1JBAIT 4 GB e-MMC NAND Flash

    • Texas Instruments 1211A1 USB 2.0 PHY Transceiver

    • Atmel MXT112S Capacitive Touchscreen Controller

    • Texas Instruments AFE4490 Integrated Analog Front-End for Pulse Oximeters

Edit Step 15  ¶ 

Image 1/1: We were a little...unimpressed by Motorola's pick.

Edit Step 15  ¶ 

  • Layered underneath the Micron RAM we found a Texas Instruments X3630ACBP (OMAP3630) OMAP 3 Applications Processor.

  • We were a little...unimpressed by Motorola's pick.

    • This is the same processor found in the Motorola Droid 2, and the MOTOACTV, Motorola's first smartwatch—2010 and 2011 tech.

Edit Step 16  ¶ 

Image 1/2: Wolfson Microelectronics [link|http://www.wolfsonmicro.com/documents/uploads/data_sheets/en/WM7121_1.pdf|WM7121|new_window=true] Top Port Analogue Silicon Microphone

Edit Step 16  ¶ 

  • The list of ICs continues:

    • Wolfson Microelectronics WM7121 Top Port Analogue Silicon Microphone

    • Texas Instruments TPS659120 PMU for Processor Power

    • Texas Instruments BQ51051B Integrated Wireless Power Li-ion Charger Receiver

    • Texas Instruments WiLink WL1831 Wi-Fi and Bluetooth Module

    • Wolfson Microelectronics WM7132 MEMS Microphones Bottom Port Analogue Silicon Microphone

    • Solomon Systech SSD2848K1 MIPI Display Interface Controller

    • On the flipside: an InvenSense MPU-6051 Six-Axis (Gyro + Accelerometer) MEMS Motion Tracking Device

Edit Step 17  ¶ 

Image 1/3: Just like before, it took a significant amount of heat to coax this LCD out of its ring.

Edit Step 17  ¶ 

  • We're back to heating and prying as we work to free the LCD.

  • Just like before, it took a significant amount of heat to coax this LCD out of its ring.

  • This isn't the special round OLED display little birds were telling us about. We're guessing this difference probably has more to do with price than design. After all, round displays are not exactly dime-a-dozen.

  • All this ring-around-the-rosie reminds us of a another round gizmo.

Edit Step 18  ¶ 

Image 1/2: We can't help but notice that it looks just like the [http://img1.wikia.nocookie.net/__cb20130302040321/memoryalpha/en/images/5/56/Constitution-class_USS_Enterprise_NCC-1701_finalized_plan_views_by_Matt_Jefferies.jpg|USS Enterprise|new_window=true], if it were missing a nacelle that is.

Edit Step 18  ¶ 

  • After being freed from the rest of the watch, the display assembly is laid out in all its glory.

    • We can't help but notice that it looks just like the USS Enterprise, if it were missing a nacelle that is.

  • The Moto 360 is the first Android Wear smartwatch to feature an ambient light sensor (for an auto-dimming screen). To save space, Motorola built the sensor into the display assembly, which explains the black bar found on the bottom of the display.

Edit Step 19  ¶ 

Image 1/3: With Jimmy in hand, we remove the charging dock's circular, rubber foot with ease.

Edit Step 19  ¶ 

  • What secrets could the Moto 360's charging dock hold? Let's find out!

  • With Jimmy in hand, we remove the charging dock's circular, rubber foot with ease.

  • With a little help from our Pro Tech Screwdriver Set, we remove four T5 screws that stand between us and inductive charging goodness.

Edit Step 20  ¶ 

Image 1/3: The dock's internal assembly is secured by a single clip, which is easily dispatched with the flick of a [product|IF145-002-2|spudger|new_window=true].

Edit Step 20  ¶ 

  • We were surprised to find that the charging dock has a decent amount of heft to it.

  • The dock's internal assembly is secured by a single clip, which is easily dispatched with the flick of a spudger.

  • The main event is an insulated inductive charging coil soldered to the charging dock's motherboard.

    • Just like the watch's charging coil sticker, this coil's gray backplate is ferrous.

Edit Step 21  ¶ 

Image 1/1: Texas Instruments [http://www.ti.com/product/bq500212A?keyMatch=Bq500212A&tisearch=Search-EN|BQ500212A|new_window=true] Qi Compliant 5 V Wireless Power Transmitter Manager

Edit Step 21  ¶ 

  • More ICs await us on the charging dock's motherboard:

    • Texas Instruments BQ500212A Qi Compliant 5 V Wireless Power Transmitter Manager

    • Texas Instruments 97376M Synchronous Buck NexFET Power Stage

Edit Step 22  ¶ 

Image 1/2: Watch band is a standard size and easily replaceable (with small enough tweezers).

Edit Step 22  ¶ 

  • Motorola Moto 360 Repairability Score: 3 out of 10 (10 is easiest to repair).

    • Watch band is a standard size and easily replaceable (with small enough tweezers).

    • Heat and careful prying is required to remove the rear panel—and then even more prying to pull out the inner housing. It is very difficult to open the device without compromising its waterproof seals.

    • The battery is trapped deep within the device, within the inner housing. Nearly complete disassembly is required to replace.

    • The display does require complete disassembly to replace, as it is removed from the back of the main bezel.

Man, I was really hoping that the pics included a scale. I'm trying to track down the length of the band and the watch itself to see if i'm going to need a longer one.

Jason Stanton - Reply

If the battery were round, it could be about 1.57 times larger than the square battery in terms of area. Let's assume the 12 hour battery life that's been reported is accurate. That means with a circular battery you could expect just shy of 19 hours of battery life.

Thank you for this. Both your disassembly and Moto's engineers' packaging are impressive.

Wish list for developing your incredible piece:

Profile pics of the motherboard and the screen, to get a perspective of the thickness.

Is the ring shaped case aluminum (which it seems to say when checking it out in online store descriptions) or stainless?

A BoM estimate would be fantastic.

Must say Motorola Engineers are AWESOME !

I don't understand the PCB though... too large for a watch that small, and the OMAP3? why?

zodiacsoulmate - Reply

"and the OMAP3? why?"

They had lots of them lying around because the Motoactv sold so poorly?

Ok, jokes aside, I believe the whole circular assembly is a pain to design and build cost-wise, so they chose the cheapest SoC possible to bring down the cost a bit. Bad choice.

kurkosdr -

yea lol... i don't even think using OMAP3 bring cost down in any way... maybe TI give them for free lol

Interesting ... the Moto 360 uses the same processor the LG Optimus Black (Texas Instruments OMAP 3630). I have this smartphone since 2011 and it works today.

Since this uses the same TI OMAP processor as the MOTOACTV then it should have wifi built in but disabled?

WL18G 31 46C1VRI looks like it is a WL1831 - TI WiLink 8.0 wireless chipset for WiFi, Bluetooth, and Bluetooth LE. It should have ANT+ too (which the MOTOACTV used).

Are there holes in the rear cover? How does the light pass through it? Which material if no holes?

Do you have some spare rear cover to sell?

Just ordered a 'WL1831MODGBMOCT-WiLink 8 Single Band Combo Wi-Fi, BT & BLE Module' from TI to see if it matches the chip above. It was free. ALL the chips in this series have wifi AND Android drivers included so a dev could have got this working a year ago... The only concern is the 0.8mA to power it with an always on rating of 1 DTIM =( Battery Draw Death!

Just in case anyone checks back here, Ive been getting about 14-15 hours with mine, using darker faces, auto brightness, and no ambient. I get a lot of tweets and texts/emails since I monitor my younger daughters' accounts, so all in all, I was pretty impressed with the battery life that I got.

Hello,

Does anyone know the PCB pushbutton manufacturer? And what about the mechanical pushbutton?

BTW, great tuto!

Thanks

Mory - Reply

How can it matter to anyone that the Moto 360 uses a TI OMAP 3630 chipset vs some new Samsung or Qualcomm chipset? It has a tiny battery so performance is really not the top priority here but power consumption. Even Samsung clocked the Galaxy Gear's Exynos CPU to 1/4th it's full speed (re-enabled with null 23 rom).

What is cool about the OMAP chipset is that TI supplies thorough documentation and the 3630 may include an IVA 2+ core, which can perform voice recognition independent of the CPU and faster than most comparable chipsets.

Ali Zubair - Reply

a special tool is not needed, and prying it free is not necessary. there are 4 little curved plastic tabs holding the inner plastic case into the outer metal case. they slot into a space next to the watch strap pin holes... there are 4 small slots on the inner case used to access the tabs (roughly 2 oclock, 4 oclock, 8 oclock, and 10 oclock position on the case in step 6 pictures),insert a very thin/sharp probe (i used tip of some tweezers) into the slot and slide toward the watch strap area... the tip of the little plastic tab should pop out. pull the rest of the tab out and repeat for the other three holes/slots. the tabs mechanically lock the inner case and outer case together... without the tabs in, the inner case will slide out with only the friction from the o-ring. no need to pry and risk damage. that should make taking the moto 360 MUCH easier to do and much less intimidating.
