Arcade Renovations I-PAC 2 Game Controller Interface with USB Cable

This interface module easily converts switch actions into standard PC-keyboard codes that many games use. I used two boards--one per game cabinet. It was easy to connect controls and have a PC display the corresponding keyboard characters. For example, if you connect a normally-open switch to an input and close the switch (the other switch terminal connected to ground) your computer "sees" the key code. The document lists the signal inputs and the key code each one generates. A USB cable provides the connection to your game-control computer.Two cautions. 1. Some key codes are nonprinting (ALT and CTRL). The I-PAC software lets you change the codes, though. 2. If you get controls with JST-connectors on the jumper wires, the copper strands are VERY small and difficult to strip carefully and to attach to the screw-down terminal strips (approx. 0.2-in centers). I suggest you use strips of pin connectors on 0.1-inch centers. (Amazon vendors sell them.)To make a group of connections, say for four joystick switches, cut a strip of 7 pins and pull out odd numbered pins. Solder the four tiny wires to the short pins and put heat shrink tubing on the four solder joint. Put the long ends into the screw-down contacts on the board and tighten the screws.

I used this as an interface for my Raspberry Pi 3. I needed a way to import signals from two 4-way WICO leaf joysticks for my homemade/RetroPie Robotron game.
