“My LED sequencer itself is quite simple but I shows you how to use the Mini PCIe connector of the MKR Vidor 4000 with a breakout board.
The Arduino MKR boards only have a limited number of GPIOs. The MKR Vidor 4000 is different because it has a FPGA to support its main microcontroller. Many of the FPGA pins are available on the Mini PCIe connector. So I took a closer look at this connector and wanted to see which functions are available at these pins.”
