Hackaday reports that OnChip launched a Crowd Supply campaign:
mRISC-V: The First Open Source RISC-V Microcontroller
Now, this is finally changing. OnChip, a startup from a group of doctoral students at the Universidad Industrial de Santander in Colombia, have been working on mRISC-V, an open 32-bit microcontroller based on the RISC-V instruction set [..]
