External LED display & control via conn1
I'm looking to build an enclosure and replicate LED and control functions. I've had the voltmeter out and i'm not seeing what I expected. Can somebody reconfirm the pins please?
I've got a rev2 board and was expecting the following (see image). I can power the board up via what I think is pin 3 but I'm not able to find +5v on any of the other pins...
