Overview

The RVPC (RISC-V Personal Computer) is an educational DIY kit designed as a minimal, low-cost computer system based on the WCH CH32V003J4M6 RISC-V microcontroller. This manual provides a complete hardware overview, including a schematic diagram, PCB layout, and a bill of materials featuring PTH components for easy soldering. The system interfaces with a PS/2 keyboard, generates VGA display output, and includes a piezo buzzer for audio. The document details software installation using PlatformIO and provides instructions for using an ESP32-S2 or Raspberry Pi Pico as a programmer. It also describes demo applications such as the RVMON memory monitor and various interactive games.

Use Cases

  • Learning RISC-V architecture and instructions
  • Educational soldering and electronics assembly projects
  • Low-cost embedded system development and testing
  • Retro-style computing and game programming
