A custom version of the blackMagic probe with rust in it

Pick the pre-built firmware for your board or build from source.

'see wiki for exact pinout' ### 3. Start debugging

Or use any GDB frontend (VS Code, CLion, etc.) — just point it to the serial port.

This project uses CMake with presets for each target platform.

There is a devpod/docker build environment included.

- CMake ≥ 3.21 - ARM GCC toolchain (arm-none-eabi-gcc) or LLVM/Clang - RISC-V toolchain (for CH32V targets) - Rust toolchain (for the GDB interface)

Swindle ch32 revJ mini: common questions

What microcontroller does the Swindle ch32 revJ mini use?

The Swindle ch32 revJ mini is built around the CH32V303RCT6, from the STM32 family.

How big is the Swindle ch32 revJ mini PCB?

The Swindle ch32 revJ mini measures 38.3 × 34 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Swindle ch32 revJ mini?

39 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Swindle ch32 revJ mini design files?

From the mean00/swindle repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Swindle ch32 revJ mini design in my own project?

The repository has no license, so all rights stay with mean00. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Swindle ch32 revJ mini without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
