The G Watch turns out to be pretty easy to take apart. There are four Torx T5 screws on the back, removing them gives you access to its internals. The 400mAh battery is integrated into the back cover. ARM’s teardown confirms 3.8V chemistry, resulting in a 1.52Wh total capacity.
The logic board in the Gear Live is a bit more complex. There’s a second layer stacked on the main logic board that also acts as an RF can.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
