Adafruit MacroPad RP2040 Starter Kit - 3x4 Keys + Encoder + OLED

The Adafruit MacroPad RP2040 Starter Kit is a complete programmable 3×4 macro keyboard powered by the Raspberry Pi RP2040 microcontroller. This all-in-one kit includes the MacroPad board, key switches, keycaps, enclosure, and hardware — ready to assemble with no soldering required.

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 shows keymaps, system stats, or custom graphics, while the rotary encoder handles volume, scrolling, or brightness control.

Key Features
