About the GateCrasher-CH32V PCB

GateCrasher-CH32V is an open source RISC-V PCB design by rmingon, published on GitHub under the MIT license. It is a 2-layer board measuring 20 × 40 mm, with 12 components from 8 distinct parts.

Its main chip is the CH32V003FxPx, from the RISC-V family. Other key parts include the SPX3819M5-L-3-3. By type, the board carries 4 connectors, 2 ICs, 2 diodes, 2 capacitors and 2 resistors.

It belongs with the rf & radio designs in this gallery.

From the project

bare-metal C implementation of a 433 MHz fixed-code (DIP switch) brute-force tool, built specifically for the ultra-low-cost WCH CH32V006 RISC-V microcontroller.

GateCrasher-CH32V is an open-source, ultra-compact 433MHz RF brute-forcer. It is powered by an ultra-cheap CH32V003/CH32V006 RISC-V microcontroller and an H34A RF transmitter, designed to fit cleanly inside the form factor of a standard garage door remote.

This repository includes a complete custom PCB design to make the brute-forcer compact, portable, and highly effective. All hardware design files are available in the /hardware folder and were created using KiCad.
