What it is
This is a super neat option to a common problem by xbst_Isik. This board comes with a preprinted case that will fit the PiCan board and is pre flashed with the firmware. All the credit on this goes to Isik.
A compact, USB drive shaped USB to CAN adapter, primarily intended for 3D printers running Klipper firmware.
