Adafruit MACROPAD RP2040 Bare Bones - 3x4 Keys + Encoder + OLED
We have ✅ 2 available of the AF-5100 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit MACROPAD RP2040 Bare Bones is a programmable 3×4 macro keyboard powered by the Raspberry Pi RP2040 microcontroller. It comes with a 128×64 OLED display, rotary encoder with push-button, speaker, and 12 NeoPixel LEDs — everything except the key switches and keycaps, so you can customise it with your preferred Cherry MX-compatible switches.
Program it with CircuitPython, Arduino, or MicroPython to create custom macros, hotkeys, emoji shortcuts, MIDI controllers, or anything else you can imagine. The OLED display can show keymaps, system stats, or custom graphics, while the rotary encoder handles volume, scrolling, or brightness control.
