Kicad files for homebrew hobbyist computer with custom RISC-V CPU
This is the hardware repo for a homebrew "personal computer" designed from scratch down to the logic gate level.
The computer is based on my custom RISC-V CPU core (pipelined, in-order, 5-stage) and has all the common peripherals you'd expect on a PC circa the early-2000s like USB, HDMI, keyboard and mouse, etc.
This repo is focused specifically on the PCBs necessary to build the complete computer.
