Once assembled each MiSTer FPGA Digital IO board is inspected under a microscope to ensure no solder bridges are present, the completed version 1.2 Digital IO board is fully cleaned in an ultrasonic bath to remove any flux residue left over from assembly, once clean the IO board is fully tested on a live MiSTer setup. Each IO board uses high quality branded components including Samsung Electro-Mechanics and Microchip Technology.

SW3 on the DE10-Nano board must be set to the ON position for the Digital IO board to function.
