From the project
Custom board designs for MiSTle projects
This board is derived from the MiSTeryDev20k board which was the first full custom board designed for the MiSTle project.
This board is a development board initially designed to test the upcoming GW3A-LV20 FPGA with the MiSTle retro computing cores. It can also be used with the existing GW5A-LV25 FPGA as seen in the image above.
The NanoMig and C64Nano had been prepared to run on the GW3A to ensure that the cores can be synthesized and especially to verify the pin mapping. Depiced above is the board with the GW5A-25K mounted and running the GW5A-LV25 variant of the NanoMig FPGA Core.
