Adding USB-C and a larger battery to a Logitech MX Master Mouse @Hackaday @Logitech @Adafruit
A retrofit by cmot17 of a Logitech MX Master upgrades the battery and USB-C. The battery was upgraded from 500 mAh to 950 mAh. The USB micro B connector was carefully cut away and an Adafruit USB-C breakout board trimmed to fit in its place. Delicate work to ensure nothing vital was cut.
Since [cmot17] didn’t change the mouse’s original electronics, the newly upgraded Logitech MX Master won’t actually benefit from the faster charging offered by USB-C. If anything, it’s actually going to charge slower thanks to the beefier battery. But considering how infrequently it will need to be charged with the upgraded capacity (Logitech advertised 40 days with the original 500 mAh battery), we don’t think it will be a problem.
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.
