This is a USB-C to 5v barrel adapter for the MiSTer FPGA console with built in switch. This is specifically for the original DE10-nano or QMTech clone as they both use a 5v barrel power supply. This isn't for the RetroRemake MiSTer Pi as it uses native USB-C power and that is available in a separate listing.
I have designed this adapter to allow you to use a USB-C power supply with your MiSTer fpga console and have the ability to power it off with a flick of the switch. It outputs 5v center pin positive just like the De10-nano requires. I would recommend a quality PSU that can supply 2 to 3 amps. Regular 5v or PD USB-C charger should work fine as long as it can supply 5 volts.
I have tested my adapter with both original DE10-nano and QMTech boards with a wide range of USB-C chargers both regular 5v only and PD ones and it works great. Feedback is always appreciated.
