I got a free batch of those, as they were returned by people who weren’t able to use them either.
I can confirm that they are not compatible with normal HUB75 panels. I used 2 teensy programmed to work with regular HUB75 panels and they worked fine.
Then I plugged them in multiple of those new panels, and nothing lit up. I made sure I was connected to the “IN” connector, but nothing lit up.
I then removed the HUB75 connector and rubbed my finger over the connector to create random signals, and got LEDs to light up.
- The panel power and LEDs work
- They are not compatible at all with HUB75 signalling as output by SmartMatrix.
I know some panels move pixels around in annoying ways, but are there known panels that don’t even light up at all?
