Pebble Teardown
Teardown
Teardowns provide a look inside a device and should not be used as disassembly instructions.
Welcome to the future of watch evolution. The Pebble E-Paper Watch is the "first watch built for the 21st century." It can track your bikerides, display your text messages, and even tell the time! We had no choice but to bust the Pebble open and see what made it tick.
Update: We did not initially find hardware evidence of Bluetooth Low Energy support, but the engineers at Pebble got in touch to clarify things. Their RF module does in fact support BLE, and they assure us that a firmware update to support this feature is forthcoming.
Waste no time! Head on over to Twitter to follow us for the latest teardown news.

Pebble Teardown
¶
-
A pebble is a small rock often thrown into ponds or lakes. The Pebble, on the other hand, is a smartwatch fueled by internet-connected apps and unlimited innovation.
-
The watch will connect to your smartphone (iPhone or Android) via Bluetooth, bringing alerts of incoming calls, emails, and texts to your wrist.
-
But what type of hardware is responsible for powering the Pebble? These are the tech specs listed:
-
144 x 168 pixel display black and white e-paper
-
Bluetooth 2.1+ EDR and 4.0 (Low Energy)
-
Vibrating motor
-
3-axis accelerometer with gesture detection
-

Step 2
¶
-
The rear side of the Pebble is adorned by lovely, gold-colored writing.
-
It is waterproof up to 5 ATM (50 meters or 165 feet), making it wearable while washing dishes, playing sports, and swimming in shallow water. 'Where is it not wearable?' you ask.
-
To protect the Pebble from water damage, the front portion is tightly fitted with a clear plastic frame and sealed tight.

Step 3
¶
-
For a watch with no visible outer screws, your first question is probably something along the lines of, 'Hey iFixit, how do you open that which cannot be opened?'
-
Our response: 'With the help of our iOpener, of course!'
-
-
With more than a little heat and some clever prying, we hope to outsmart the world's smartest watch.
Edit
Step 4
¶
-
Pebble employs tons of adhesive to keep water—and tinkerers—out. Add in a bezel around the screen, and it's impossible to separate the cases without compromising the display.
-
With plenty of elbow grease and our iSesamo, we get our proverbial foot in the door and start prying this Pebble open.
-
We manage to part the cases, leaving the stubborn smartwatch in only slightly better condition than if we had bombarded it with actual pebbles until it popped open.

Step 6
¶
-
While there is no exact definition for what makes a display technology e-paper, it essentially entails paper-like readability in ambient light and very low power draw. The Pebble makes use of a new Sharp Memory LCD that puts it in the realm of e-ink and e-paper.
-
The display is capable of maintaining its current image with very low power draw (less than 15 μW for a static image, according to the manufacturer).
-
Peeling up the Pebble's e-paper display film reveals backlight LEDs. The small display only requires three LEDs (controllable by a wrist gesture) to light its face.
Edit
Step 8
¶
-
Just a swish and a flick of the spudger and the lone ribbon cable surrounding the whole assembly is freed.
-
The cable's adhesive also secures the backlight guide, allowing the LEDs to shine on, providing backlighting for the e-paper screen.
-
We learned in our Nook Simple Touch with GlowLight teardown that light guides work by bouncing light shined in one end through a diffraction grating to provide an even glow—in this case beneath the e-paper display.
