The digital IO board V1.2 for Mister FPGA is an optional expansion that can be used by plugging into the top of the Terasic DE10-Nano SoCand allows for dual SDRAM modules. It has a USB 3.0 connector which support for Sega Mega Drive / Genesis / Master System game pads using a SNAC adapter board. ? Note: The SW3 switch on the DE10-Nano mainboard must be flipped into the ‘On’ position before the digital IO board will operate correctly. It adds the following features to the MisTer Platform: * Suitable for Terasic DE10-Nano FPGA Board * Built-in On / Off Power Switch * Digital TOSLINK Connector * 3.5mm for Analog Audio (Tape Input) * 3 User Buttons & 3 Status LEDs * Secondary MicroSD Slot * User I0 Port Connector FAQ: * Q: What is the function of the analog audio input interface on the IO board? * A: This interface is mainly use external audio device as a tape input. * E.g: TRS-80 Model I cassette * Q: Where headers for external push buttons & LEDs? * A: 5pin white serial port connection button, 7pin white serial port connection LED See more
