LoFive is a lightweight SiFive Freedom E310 open source SoC evaluation kit. The E310 leverages the Free and Open RISC-V Instruction Set Architecture originally developed by UC Berkeley and now has wide industry support via the RISC-V Foundation.

Don't let the board's understated name and openness fool you - this MCU packs some impressive specs and the board was designed by the prolific QWERTY Embedded Design founder, Michael Welling.
