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. Connect the JAMMA connector 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.
