It's the perfect io board for:






JAMMIX is the complete solution for users that want an ITX form factor or a JAMMA edge for MiSTer.

  • Hundreds of ITX / DTX / ATX case options available on the market

  • Simultaneous buffered RGB output via JAMMA and “VGA” port

  • Sync-On-Y circuit, for Component output via "VGA" port (JAMMA RGB output not available in Component mode)​

  • JAMMA RGB levels are 4V (p-p), for best compatibility with standard arcade monitors  with buffered TTL Csync output on JAMMA edge

  • Onboard Stereo audio amp, for Neo Geo style cabinets. Neo Geo MVS harness compatible 

  • I2S audio DAC for higher quality analog output

  • Buffered Audio line-out

  • Audio line-in (no need for the standard ADC addon)

  • Onboard USB 2.0 hub. Four External USB 2.0 ports, two on an internal header


  • Ethernet routed to the IO shield

  • Self-resetting (PTC) fuses on all USB ports, DE10 Nano, and User port (SNAC)

  • Overvoltage protection on the 5V rail, to help protect the DE10, USB devices, and JAMMIX (OVP works whether using JAMMA, ATX, or 5V DC jack)

  • Multiple power options ATX, JAMMA or  5V DC jack

  • ATX power with soft power on/off, and front panel buttons/LEDs headers (soft power option also available when powered via JAMMA or 5V DC jack)

  • JAMMA edge connector, with “Gold fingers”  and beveled edge, to prevent damage to the harness socket

  • Support for the extra “CHAMMA” style button inputs, for up to six buttons per Player 1 & 2

  • CPS2 style "Kick" header, with 22 extra player control inputs, including configurable support for Players 3 & 4

  • Replicates the functions of the v6.1 IO Board (LED outputs and button inputs are available on the front panel header. Secondary SD signals broken out to a header.)

  • Mounting holes for 2.5" HDD/SSD

  • Expansion board addons for enhanced IO available in the future.

JAMMIX is shown below in a console-like ITX case. Gone are the days of awkward cases, untidy-looking cables and dongles out of all sides of your MiSTer setup.


JAMMIX does not stop there, it's also the ideal all-in-one MiSTer solution for arcade cabs, with its beveled JAMMA edge, audio amp, USB ports, and simultaneous output of both analog and digital video.

Please note: Pictured ITX case not included.

The internal height of the chosen case needs to be a minimum of 80mm, to allow for fan clearance / airflow.


A 20mm x 20mm x 10mm heatsink is included  for the FPGA on the DE10 Nano.
