About the Libre-MiG MCU PCB

Libre-MiG MCU is an open source STM32 PCB design by JustEnoughDucks, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 130 × 55 mm, with 50 components from 23 distinct parts.

Its main chip is the STM32F072CBTX, from the STM32 family. Other key parts include the MCP6004 and ADP122AUJZ-3.3-R7. By type, the board carries 19 capacitors, 11 switches, 7 connectors, 7 resistors, 3 ICs and 2 jumpers.

From the project

Open Source Joystick/Open Source Flightstick that combines the Olukelu Gimbal with a MiG-31 inspired Flightstick designed for Star Citizen or space simulators

I saw few options for open-source flight sticks out there. Commercial options are exceedingly expensive. I strive to build a full-featured and high-quality Flightstick with a target BOM cost from 150-200€. It is not meant to be the cheapest joystick, but it does aim to be the most attractive option for open-source and DIY enthusiasts.

BOMs, parts lists, and documentation for various gimbals and 3D printed joysticks are sparse at best. I aim to include an extremely comprehensive requirements list, drop-in replacement part list, etc... so that this will be as accessible to everyone who has…

Libre-MiG MCU: common questions

What microcontroller does the Libre-MiG MCU use?

The Libre-MiG MCU is built around the STM32F072CBTX, from the STM32 family.

How big is the Libre-MiG MCU PCB?

The Libre-MiG MCU measures 130 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Libre-MiG MCU?

50 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Libre-MiG MCU design files?

From the JustEnoughDucks/LibreMiG-S repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Libre-MiG MCU design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which JustEnoughDucks chose for the repository.

Can I test firmware for the Libre-MiG MCU 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.
