20-Pin Multiplier Kit (for RETRO Board + UFB)

IMPORTANT NOTE:  If you are dual modding the Brook Universal Fighting Board and the Retro Board, you will want to set the Retro Board as the default board at boot up (by using the jumper) as this will allow you to perform firmware updates on both the UFB and the Retro Board.  If the UFB is the default setting at boot up, the Retro Board cannot be updated

This kit allows you to dual mod your arcade stick to work with both the Brook Universal Fighting and Retro Board using one USB output to your arcade stick.  

Up to this point, dual mods required either a switch or two USB outputs, one for each board.  With this kit, you’ll be able to toggle between the two boards.  

The first piece is the 20-pin multiplier which was designed by our partner, Jasen’s Customs.  This is a 3-port multiplier that would link the 20-pin from each of the boards (Brook UFB and Retro) and the 3rd port to use our custom 20-pin harness for arcade sticks.  

The 20-pin male connectors on each board will be linked with the 20-pin female ribbon cables to the multiplier.  Additionally, the 4-pin will be connected between the two boards that will allow you to toggle between the two.
