RISC-V silicon available, and pcbs

By

In another monumental eye-off-the-ball experience, I failed to notice that SiFive have released a chip implementing a 32bit version of the RISC-V architecture, and an Arduino-esk development board to go with it. Called the Freedom E301 or FE310, alongside the RISC-V core are a whole bunch of peripherals (see diagram). The core runs at 320MHz, …
