Non-motion MCU is a project that is made for Voron 0. It is driven by Raspberry Pi Pico / Pico 2, and can only be run off of micro USB / USB-C. It was a part of the mobile Voron 0 project that didn't seen lights of day. And because I never look at when-will it release, it took around two years to release.
The current generation-revision is 1.2.
Non-motion MCU was made after a prefboard of similar which had a lot of wires. I wanted to simply and extend this kind of board but without the complication of the wires.
The prefboard in question has a connector made specifically for V0 Simple Display, the input shaper port and four IO ports with ground right next to one of them.
Non-motion MCU has nine ports, including:
- an input shaper accelerometer port,
- LED ports,
- an external power (to MOSFET) port,
- two thermometer ports,
- a dedicated SPI port,
- miscellaneous port,
- a port made specifically for revision 2 of hart.k's Voron 0 Simple Display.
It supports Raspberry Pi Pico and Raspberry Pi Pico 2 1.
An IDC 10P in 2.54mm oppose-facing connector is required. This is commonly seen as expansion cables for 3D printers during early days of RepRap 3D printing.
Please check the assembly manual when building the unit yourself.
It can only be powered through USB of Pi Pico. Duh, it has no other proper methods of being powered.

Non-motion MCU was made before Pi Pico 2, let alone Klipper supporting RP2350 on Pi Pico 2. ↩
