To our dismay, we could not examine the deep dark innards of the Hero3 through the lens. Time to crack it open! Peeling off the water resistant port cover reveals the following ports: Mini USB Micro HDMI microSD http://d3nevzfk7ii3be.cloudfront.net/igi/oficAdqyUBefiTgj http://d3nevzfk7ii3be.cloudfront.net/igi/jcYQTXvRPxD6TcaF http://d3nevzfk7ii3be.cloudfront.net/igi/WdvUfSGYqlgae3wb With the simple press of a button, the back cover is free, allowing access to—what's this—a battery pull tab? It's almost as if the folks at GoPro wanted you to be able to take the battery out of your HD Hero3. What a novel idea. The Hero3's 3.7 V battery is rated at 1050 mAh/3.85 Wh, a 50 mAh decrease from previous models, presumably due to the device's smaller size. As usual, caution labels on the back of the battery warn us not to store the battery in high temperatures, disassemble it, or dispose of it…<a href="http://www.youtube.com/watch?feature=player_detailpage&v=V2vpdoMuTQg#t=8s" rel="nofollow">with fire</a>. Thanks for the heads up, GoPro. http://d3nevzfk7ii3be.cloudfront.net/igi/xD63gITMwqFPsXP6 http://d3nevzfk7ii3be.cloudfront.net/igi/KPAYjqdNbHbQOZxR http://d3nevzfk7ii3be.cloudfront.net/igi/DNAlJVbxVXMYyhPD It has come to that time in the teardown where we finally have to reach for a tool. Not just any tool, but the always-appropriate <a href="/Tools/Plastic-Opening-Tools/IF145-000?utm_source=ifixit_guide&utm_medium=wiki_text&utm_term=if145-000&utm_content=product_link">plastic opening tool</a>. A few clips and a little bit of adhesive are no challenge for our trained hands, and the front cover lifts right off. http://d3nevzfk7ii3be.cloudfront.net/igi/qYjFUlOMJnQ6BLeU http://d3nevzfk7ii3be.cloudfront.net/igi/cboko3aPVSfwwGho We are through the adhesive and on to some of our favorite little repair-friendly friends: Torx screws! Four surprisingly-long (8.1 mm) T4 Torx screws hold the midframe in place, and are easily removed with the help of our <a href="/Tools/54-Bit-Driver-Kit/IF145-022?utm_source=ifixit_guide&utm_medium=wiki_text&utm_term=if145-022&utm_content=product_link">54 Bit Driver Kit</a>. http://d3nevzfk7ii3be.cloudfront.net/igi/T1ruXf2gMfmEc2Zg http://d3nevzfk7ii3be.cloudfront.net/igi/MQxXPPUBqqjGwVGN A little more prying, and the midframe and motherboard assembly is the next piece to practically fall off the GoPro. This is almost too easy. We have always pushed for product design that favors repairability, but seeing it in action still makes us do a double take. http://d3nevzfk7ii3be.cloudfront.net/igi/jiJlhElKA4bLgE51 http://d3nevzfk7ii3be.cloudfront.net/igi/XFZx1VQdvSUdt3iD Two pieces of tape, one connector, four more screws, a little bit-o-prying…this device is coming apart pretty easily considering the small package and large recording ability! http://d3nevzfk7ii3be.cloudfront.net/igi/vVHpDXAvGC3wgDCk http://d3nevzfk7ii3be.cloudfront.net/igi/YFBZymUxWOCRiNAx http://d3nevzfk7ii3be.cloudfront.net/igi/ZeQO6B1vXWhTETnI The image sensor pops off the motherboard assembly and can be replaced independently of the rest of the ICs. This Hero is gaining repairability cred left and right. Our Hero3 Black Edition comes with a 12 megapixel image sensor with improved low light capabilities, a step up from the 5 and 11 megapixel modules in its other Hero counterparts. While more resolution is great for stills, the pixel-crunching power that sets the Black Edition's video skills apart from the rest of the pack are in the image processor—more on that later. http://d3nevzfk7ii3be.cloudfront.net/igi/QWVIdkfQeX5HJZaR http://d3nevzfk7ii3be.cloudfront.net/igi/pDQlsJkpWuQMOtOy At the heart of the GoPro lies a <a href="http://www.sony.net/Products/SC-HP/cx_news/vol70/pdf/imx117cqt.pdf" rel="nofollow">Sony IMX117</a> image sensor. According to our pals at <a href="http://www.chipworks.com" rel="nofollow">Chipworks</a>, the Exmor-R sensor features a "1.55 µm back illuminated design on a ceramic substrate"—cool! The sensor supports 12 MP imaging at up to an impressive 35 fps, even though the camera advertises a burst rate of 30 fps.

We decided to have a little bit of fun with the Hero3's lens and one of our <a href="/Tools/iFixit-Opening-Picks-set-of-6/IF145-123?utm_source=ifixit_guide&utm_medium=wiki_text&utm_term=if145-123&utm_content=product_link">iFixit Guitar Picks</a>. For this simple demonstration, we placed a guitar pick in front of the lens upside-down and looked through the glass. As you can see, the upside-down graphic has been flipped right-side up! So, if the lens flips the image, why aren't all of the pictures from our digital cameras inverted? Well, just like the lens of our eyeball, anything viewed through an optical lens appears upside-down until it's fed through a processor of some kind. For a digital camera, that processor is an integrated circuit. Our vision, on the other hand, utilizes the most advanced processor in the world to flip the image around: the human brain. http://d3nevzfk7ii3be.cloudfront.net/igi/yikjCFMQNPMSZKXv http://d3nevzfk7ii3be.cloudfront.net/igi/lXF4VAI31OVfO1wl Another daughterboard flies off the main assembly; this time it's the microSD and accessory board. If you've never used a GoPro, this large port might look pretty foreign to you. It's okay, you're not alone. The proprietary port is used for a variety of GoPro accessories, including a <a href="http://gopro.com/hd-hero-accessories/lcd-touch-bacpac" rel="nofollow">fold-out LCD attachment</a>, <a href="http://gopro.com/hd-hero-accessories/hero3-battery-bacpac" rel="nofollow">extended battery</a>, and various A/V adapters. http://d3nevzfk7ii3be.cloudfront.net/igi/LAmBJE2ynfLOHttO http://d3nevzfk7ii3be.cloudfront.net/igi/PcBfXhc4ZAAgVXlO http://d3nevzfk7ii3be.cloudfront.net/igi/5KLUHFQPQbR15vr6 No new tricks here, either. Removing the motherboard requires no more than a spudger and a Phillips #0 screwdriver. Most components in the Hero3 use very little power and generate minimal heat. This light coating of thermal compound on the image processor is the most aggressive cooling feature in the device. http://d3nevzfk7ii3be.cloudfront.net/igi/VpkDhPtHTKUQODc3 http://d3nevzfk7ii3be.cloudfront.net/igi/ZAZmDhZYFZbCmbkK http://d3nevzfk7ii3be.cloudfront.net/igi/Zy2TTVhO16yoXkmr Chips on the motherboard: ChipSiP <a href="http://www.chipsip.com/archive/CT49.jpg" rel="nofollow">CT49248NS962D</a> 1 Gb NAND flash + 4 Gb DDR3 SDRAM Ambarella <a href="http://www.ambarella.com/news/24/74/Ambarella-A7-IP-Camera-SoC-Brings-1080p60-Performance-into-the-Video-Surveillance-Mainstream.html" rel="nofollow">A770</a> camera system-on-a-chip Austriamicrosystems <a href="http://www.ams.com/eng/Products/Power-Management/Power-Management-Units/AS3713" rel="nofollow">AS3713</a> system PMU with backlight driver Freescale Kinetis <a href="http://bit.ly/W51hoe" rel="nofollow">SCK20DN51Z</a> USB controller Qualcomm Atheros <a href="http://www.qca.qualcomm.com/corporate/content.php?nav1=119&news=268" rel="nofollow">AR6233GEAM2D</a> 802.11n + Bluetooth 4.0 controller AC3029 http://d3nevzfk7ii3be.cloudfront.net/igi/neZRqLl5pHDVSKlS http://d3nevzfk7ii3be.cloudfront.net/igi/atOwUKv6GNue3AtK More tape, more screws, <a href="http://smilepanic.com/wp-content/uploads/MOAR8.jpg" rel="nofollow">moar</a> fun! A few more Phillips screws stand in the way of pulling out the "ultra sharp ƒ/2.8 6-element aspherical glass lens." Honestly, we just had a lot of fun looking at our guitar picks through this lens—here's another look through the Hero3's eye now that it's free of the motherboard. Because why? Because <a href="/Teardown/Samsung+Galaxy+S+4G+Teardown/4977/2#s22394">sc</a><a href="/Teardown/Nook+Simple+Touch+with+GlowLight+Teardown/9301/2#s36033">ie</a><a href="/Teardown/Apple+A6+Teardown/10528/1#s38329">nce</a>. http://d3nevzfk7ii3be.cloudfront.net/igi/BhVRQFQIBL6wAOuZ http://d3nevzfk7ii3be.cloudfront.net/igi/x2R6yhUZJPqfPtD1 http://d3nevzfk7ii3be.cloudfront.net/igi/S3RvEHHGCswrRRac There are only a few components left around the device casing. Last on the midframe is the LCD and its soldered-on cable. Repairability takes a hit here, when we have to pull out a <a href="/Tools/Heat-Gun/IF145-031?utm_source=ifixit_guide&utm_medium=wiki_text&utm_term=if145-031&utm_content=product_link">heat gun</a> and <a href="/Tools/Metal-Spudger/IF145-012?utm_source=ifixit_guide&utm_medium=wiki_text&utm_term=if145-012&utm_content=product_link">metal spudger</a> to loosen the adhesive securing this cable to the midframe. The rear case's last component is the button/speaker assembly which is attached to the backing of the battery compartment. A couple of screws and some tape hold it in place. http://d3nevzfk7ii3be.cloudfront.net/igi/Q2xPkgJEMRbOGAkG http://d3nevzfk7ii3be.cloudfront.net/igi/ZWGLn42bRdrY6QEy http://d3nevzfk7ii3be.cloudfront.net/igi/urZKkLeFxVZqPghu GoPro HD Hero3 Repairability Score: 7 out of 10 (10 is easiest to repair) The battery is intended to be easily replaced by the user, and requires no tools to access. The entire device can be disassembled with readily-available tools. Modular design throughout allows replacement of several individual components. Minimal adhesive securing the front cover can be difficult to separate, but poses no real challenge to opening. Fragile copper grounding tape can be difficult to peel and replace. Because the display cable is adhered to the midframe, replacing the LCD requires use of a heat gun. http://d3nevzfk7ii3be.cloudfront.net/igi/oLI2qeLcFfeCh6UX http://d3nevzfk7ii3be.cloudfront.net/igi/DqL1dmQXTfisgQfF
