Two firmwares for an Arduino Pro-Micro used in a 60% keyboard. The keyboard switches are connected in a matrix with diodes are each switch. Each row and column is connected to a I/O pin on the ...

This fork adds compatibility for the Pro Micro nRF52840 board to the n-able Arduino core. It works in conjunction with the platform-n-able-pro-micro-nrf52840 platform to provide full PlatformIO ...

Inside this open-source banana is that perennial favorite for macro pads, the Arduino Pro Micro, and eight switches that are wired up directly to input pins.

PD Micro is the first Arduino-compatible board with USB Type-C Power Delivery, which allows your project to make use of voltages from 5-20 V.

Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, but then had an epiphany — why not use keyboard ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.
