The Pi-MMS expansion cartridge is an easy way to add a Raspberry Pi to your MiSTer Multisystem, allowing you to enhance your retro game play on a number of MiSTer cores. This expansion is fully compatible/comparable with the MT32Pi for MiSTer.

This expansion cartridge slots into the MiSTer Multisystem with no additional power supplies or cables required.

What you will receive:

  • Pi-MMS PCB with OLED display
  • 3D printed cartridge case in red
  • All screws & buttons needed to operate the system

The PI-MMS expansion cartridge is assembled and ready to use (you need to provide and fit the Raspberry Pi Zero 2 / Zero 2W).

We recommend the Raspberry Pi Zero 2 without headers (not included) to use with the Pi-MMS. The board is compatible with other Pi products but the case is designed around the Pi Zero range. You will need to solder your Pi Zero to the Pi-MMS PCB to use the Pi-MMS.

The Pi’s Mini HDMI and USB ports are accessible on this cartridge, as is the SD card slot.
