About the LnBMP stm32 PCB

LnBMP stm32 is an open source STM32 PCB design by mean00, published on GitHub. It is a 2-layer board measuring 52.6 × 33 mm, with 33 components from 22 distinct parts.

Its main chip is the STM32F103CBTx, from the STM32 family. Other key parts include the LM1117-3.3. By type, the board carries 9 capacitors, 9 resistors, 4 connectors, 2 ICs, 2 crystals and 1 diode.

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

From the project

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)

LnBMP stm32: common questions

What microcontroller does the LnBMP stm32 use?

The LnBMP stm32 is built around the STM32F103CBTx, from the STM32 family.

How big is the LnBMP stm32 PCB?

The LnBMP stm32 measures 52.6 × 33 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LnBMP stm32?

33 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the LnBMP stm32 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 LnBMP stm32 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 LnBMP stm32 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.
