Fomu is Funded!

Thanks to everyone who’s contributed so far, Fomu is now fully funded! Thanks to your help, we will get the chance to produce an FPGA for your USB port. The campaign still has just over five weeks to go before we conclude, but already you’ve helped us meet our goal.

Keep spreading the word! Help us bring tiny FPGAs to even more people.

Product Choices


Fomu for One

An FPGA for your USB port! Includes one pre-flashed Fomu and a plastic case. The price will increase once the campaign is over, so back us today!


For Me, For You, Fomu

Projects are better with a friend. Or maybe you want to have a spare. Either way, you will receive two pre-flashed Fomu boards with plastic cases. This low price will increase after the campaign finishes!


Fomu Ten-pack

Ten of our pre-flashed Fomu boards with plastic cases, each designed to fit into a single USB Type-A port. Bring FPGA development with you wherever you go, and share your RISC-V projects with up to nine other people.


Fomu EVT Board

An EVT board revision is used to validate the schematic is correct, and to help develop the software. This EVT board is what we'll use to develop the USB stack and to make sure we've got the power and other hardware parts wired up right. Designed to mount onto a Raspberry Pi to upload a bitstream and debug the CPU.This is a limited-time production board, and won't be produced after the few remaining sell.
