an rp2040 devboard. GPIO pinouts should be the same as / similar to the pi pico, with a few extra pins
there is also an LED which could be used as a status indicatorr

routing the PCB was a pain... especially since the footprint for the flash was bigger than the easy EasyRP2040 guide
both usb routes are the same distance like requiredd
