I ordered a 5A-75B but seller send me a E80 receiving card...

https://www.colorlightinside.com/Products/i%20Receiving-series/34_133.html

Do you know if they are the same pinout ?? All the JTAG pinout seems to be same : J27, J31, J32, J30 Power is still J33, J34

Only different is the buffer chips are MW245B ... E80 buffer IC

Thanks

After some probing, it uses the same ETH as hardware V8.0 n the same pinout on J2 as V8.0

Colorlight E80 Eth Phy Managed to display something on LED panels on J2

@stanleyseow Hi, what FPGA chip on E80? Lattice or Xilinx?
