I'm using the OPL2 board with Raspberry Pi 400, but it's not entirely clear whether the numbers provided on the connection instructions are the pin numbers or the GPIO numbers.
I've assumed pin numbers, as the connection info refers to pins 2 and 6 for 5v and ground, but it would be helpful to have clarification while troubleshooting.
