An FPGA board that fits inside your USB port

Conclusion of the Fomu Campaign

Now that the campaign has wrapped up, we’ll get to work on the final version of the board. Chinese New Year is upon us, which means the factories we’re working with are all closed. That just means that it’s time to work on software, documentation, and user experience testing. We want to make sure Fomu works on any USB port you use it with, especially since the final Fomu design is more difficult to assemble and reprogram than Tomu or the hacker versions of Fomu.

Once again, thank you for helping to make this product a reality, and we can’t wait to bring the final version of Fomu to you.
