Raspberry Pi RP2040 development board doubles as a magnetic rotary encoder
PICO DEV M3 is a round-shaped development board based on a Raspberry Pi RP2040 dual-core microcontroller and serves as a magnetic rotary encoder with a few 3D printed parts.
Designed by Ahmsville Labs, the board comes with 2MB QSPI flash, various through holes for GPIOs, a USB-C port, and the magnetic rotary encoder supports up to 36,000 steps per revolution and comes with 18 individually addressable LEDs.
