What RISC-V boards are built for
Open source RISC-V boards: common questions
Where can I find open source RISC-V boards?
This page lists 4, each read from its KiCad files on GitHub: board size, layers, the full parts list and a render of the PCB, with links to the original repository.
How big is a typical RISC-V board?
The median is 55 × 95 mm, and 50% are two-layer designs.
What is the most popular open source RISC-V board?
By GitHub stars, Workbench-1 Controller by Quchaosheng, with 129 stars.
Can I simulate one of these RISC-V boards before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
