Fomu, I’m
I’m Fomu, an FPGA in your USB port! I have 128 kilobytes of RAM, and enough logic cells to run a RISC-V CPU and a USB softcore. I have four contact pads that can easily be used to make two buttons. And I have an RGB LED, because everyone loves blinky things!
I’m available for order now on Crowd Supply.
Workshop from CCamp19, RISC-V 2019 Summit and 36C3!
