some board & modules made by Colorlight are based on Lattice ECP5 series, which are supported by open source toolchain (yosys & prjtrellis & nextpnr), can be used to make very interesting project. current focus on Colorlight i5-v6.0 & i5-v7.0, i5-v7.0 is the latest, and can long-term supply, and the pinout of i5-v7.0 is same as i5-v6.0. check get-start to see how to setup the env and program the bitstream.
