About the Risc cluster PCB

Risc cluster is an open source RISC-V PCB design by rmingon, published on GitHub. It is a 4-layer board measuring 81 × 62 mm, with 166 components from 15 distinct parts.

Its main chip is the CH32V003F4P6, from the RISC-V family. Other key parts include the AMS1117-3.3, CH340C and CH32V307RCT6. By type, the board carries 55 capacitors, 53 resistors, 27 ICs, 25 diodes, 5 connectors and 1 crystal.

It belongs with the usb & debug tools designs in this gallery.

From the project

A distributed computing cluster based on CH32V RISC-V microcontrollers with Ethernet connectivity.

A distributed computing cluster based on CH32V RISC-V microcontrollers with Ethernet connectivity.

This project implements a cluster computing system using multiple CH32V microcontrollers connected via Ethernet. The system features a master controller (CH32V307RCT6) that coordinates with multiple worker nodes (CH32V003F4P6) to form a distributed computing network.

Risc cluster: common questions

What microcontroller does the Risc cluster use?

The Risc cluster is built around the CH32V003F4P6, from the RISC-V family.

How big is the Risc cluster PCB?

The Risc cluster measures 81 × 62 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Risc cluster?

166 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Risc cluster design files?

From the rmingon/risc-cluster repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Risc cluster design in my own project?

The repository has no license, so all rights stay with rmingon. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Risc cluster without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
