Similar to the BTT Manta boards (#551), this is a 3D printer controller board that accepts a CM4 for an all-in-one Klipper setup.
The interesting thing about this one is that it also has a 40-pin connector, so you can stick it on top of a full-size Pi instead.
It can also be used with any other SBC or PC over USB, though only with Klipper (it uses an RP2040, which Marlin doesn't currently support). The RGB, servo, and two of the fan connectors won't work in this mode, since they're wired directly to the Pi or CM4's GPIO pins.
