RGB-Pi JAMMA Installation

Steps

1. DO NOT SKIP THIS STEP. Insert the ┳ piece in pin 7 of the female JAMMA harness

2. With the RGB-Pi board still DISCONNECTED, turn on the cabinet and adjust the voltage in pin 3 to 5.25v

3. If you have an electronic coin acceptor, check that it is not sending any voltage through the pin 16 or T (mechanical coin acceptor users can skip this step)

4. Connect the RGB-Pi board to the Raspberry with the JAMMA connector facing to the outside of the Raspberry Pi

5. Put a heatsink on the golden part indicated with the heat symbol (you can use regular Raspberry heatsinks)

6. WITH THE MACHINE OFF connect the JAMMA RGB-Pi to the arcade cabinet. DO NOT PLUG ANY USB POWER ADAPTER TO THE RASPBERRY PI

7. That's all! For instructions on how to install RGB-Pi OS, please visit the corresponding section in this wiki.
