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)

Zero r2 mini w5500: common questions

What microcontroller does the Zero r2 mini w5500 use?

The Zero r2 mini w5500 is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Zero r2 mini w5500 PCB?

The Zero r2 mini w5500 measures 37.3 × 63.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Zero r2 mini w5500?

45 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Zero r2 mini w5500 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 Zero r2 mini w5500 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 Zero r2 mini w5500 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
