Item Type: Digital IO Board Material: PCB For MiSTer Digital IO Board v1.2 Details: The For MiSTer FPGA Digital v1.2 I O Board is an optional expansion that can be used by connecting to the top of the For Terasic DE10 Nano SoC and allows dual SDRAM modules. It features a USB 3.0 connector and supports For Sega Mega Drive, For Genesis, For Master System game controllers using the SNAC adapter board. 1. EXPANSION BOARD: The For MiSTer FPGA Digital IO Board v1.2 is an optional expansion that connects to the For Terasic DE10 Nano SoC. 2. OPTIONAL: The For MiSTer IO Digital Board v1.2 includes a switch to select 3.3v or IO on the user IO port. 3. WIDE COMPATIBILITY: Select IO to support For Sega Mega Drive, For Genesis, For Master System game controllers using the SNAC adapter board. 4. VARIOUS FUNCTIONS: 3 buttons with different functions, 3 status indicators. Extra memory card (for some cores). 5. PRECAUTIONS: The Digital IO module has an expansion port (in the form of a USB 3.0 port, but not USB!). With a 3.5mm jack for TOSLink. 6. EASY INSTALLATION: The Digital IO module has a fan for cooling the FPGA and comes with 1 screw hole. Easy to install. 1 x Digital IO Board 1 x Fan 4 x Screws 4 x Nuts The SW3 switch on the DE10 Nano motherboard must be switched to the "On" position before the Digital IO Board can function correctly. It adds the following features to the For MiSTer platform. For Terasic DE10 Nano FPGA Board Includes quiet fan Built-in on/off power switch Digital For TOSLINK connector 3.5mm For analog audio (tape recording input) 3 user buttons and 3 status LEDs Extra Micro Storage Card slot User IO port connector FAQ: Q: What is the purpose of the analog input connector on the IO board? A: This interface is primarily used as a tape recording input for external audio devices. Example: TRS 80 I dark box. Q: Where are the connectors for the external buttons and LEDs located? A: The 5-pin white serial port connects to the push button, and the 7-pin white serial port connects to the LED.
