LED8 is a simple 8 LED module with a 12-pin Pmod™ compatible header.
This repo contains schematics, pinouts and example gateware.
Find more information on the LED8 product page.
Building the example requires Yosys, nextpnr-ice40 and IceStorm.
Assuming they are installed, you can simply type make to build the gateware, which will be written to output/count.bin. This example targets the Riegel FPGA board but can be easily adapted to any FPGA board with a 12-pin PMOD connector.
