A board designed to help make building a joystick for a Neo Geo easy and clean. This design uses terminal blocks with a 5mm pitch.

The design has screw terminals for each line from the DB15 connector as well as terminals for each button and the joystick. There is also space for an LED (powered by the +5v from the Neo Geo) and an extra terminal for the +5v line in case you want to do something with that.

The board is designed for use with Phoenix Contact’s Combicon PT series 5mm terminal blocks (however others with the same pitch will most likely fit). There are 6 2 position blocks for the buttons (+1 extra if you want one for +5v). There is 1 5 position terminal block for the joystick and 1 15 position terminal block for the DB15 in from the system. You could use the board just fine without populating the terminals (soldering directly to the holes for the terminals) but if that’s your goal a nicer and smaller board could be made with just pads/holes.

Note: The LED (including its resistor R1) and the +5v terminal block are completely optional.
