Hi, where’d you get these panels? I can find some similar ones on Aliexpress, but they don’t have a HUB75 connector. These likely use a separate clock and data line on the address pins to send addresses and possibly commands. Search the forum for AB or ABC panels and you’ll find some discussion.
I’ve been trying to get a panel with addressing like this for a while with no luck. It looks like it’s around $120-140 for me to get one, a little pricy but might be worth it if I can use it for testing. https://github.com/hzeller/rpi-rgb-led-matrix supports this type of panel. The ESP32 SmartMatrix Library port has a possibility of handling them, but I haven’t written the code and I don’t have any panels to test with. The way the Teensy using SmartMatrix Library send out address information doesn’t lend itself to driving these types of panels.
Also, I’ve never seen a panel with dimensions that aren’t a power of 2. I’m guessing there will be at least a couple places in SmartMatrix Library that need to be modified to handle non power of 2 dimensions to drive this panel, once the addressing is figured out.
