From the project

Hardware design and verilog sample files for Lattice ICE40 development boards and expansion boards.

Hardware design and verilog sample files for Lattice ICE40 development boards and expansion boards.

There are 2 core boards, one based on an ICE40 HX4K with 96 available IO pins, and another based on an ICE40 HX8K with 192 available IO pins.

The core boards are "vanilla" with minimal on board peripherals. Almost all IO pins are routed to mezzanine connectors. Expansion boards can be mixed and matched for different projects, while reusing the core board. The expansion boards can be daisy chained.
