[Phil Barrett] designed a new CNC controller breakout board called the PicoCNC which uses the Raspberry Pi Pico RP2040 module and grblHAL. It packs a bunch of features typical of these controllers,… ...

The board brings you everything you might want from a typical MCU breakout – an onboard 3.3V regulator, USB series resistors, a 1.5K pullup, decoupling capacitors, and a USB-C port.

It looks like ‘phil-barrett’ is co-operating, and developing a breakout board called PicoCNC that will accept a Raspberry Pi Pico and convert its IO to the correct voltages for driving four stepper ...
