About the Micromouse Gen1 ClubProject PCB

Micromouse Gen1 ClubProject is an open source STM32 PCB design by kevinyan0620, published on GitHub. It is a 2-layer board measuring 80 × 100 mm, with 105 components from 37 distinct parts.

Its main chip is the STM32 Microcontroller, from the STM32 family. Other key parts include the Voltage Regulator, H Bridge and MOSFET. By type, the board carries 33 resistors, 31 capacitors, 9 ICs, 7 connectors, 6 transistors and 6 diodes.

It belongs with the sensors designs in this gallery.

From the project

An award-winning, STM32F205-based autonomous Micromouse featuring a custom 2-layer PCB, 9-DOF IMU motion tracking, and C-based flood-fill navigation algorithms.

This repository details the hardware and firmware design of a Generation 1 autonomous Micromouse. Built from scratch, the project encompasses component selection, schematic capture, 2-layer PCB layout, and embedded C programming.

Here is some pictures of our PCB design and our Micromouse!

Competition Result: Placed 5th Nationally and 2nd Schoolwide at the All American Micromouse Competition (AAMC). See It In Action: Watch our competition run on AAMC Live (starts at 51:30)

Micromouse Gen1 ClubProject: common questions

What microcontroller does the Micromouse Gen1 ClubProject use?

The Micromouse Gen1 ClubProject is built around the STM32 Microcontroller, from the STM32 family.

How big is the Micromouse Gen1 ClubProject PCB?

The Micromouse Gen1 ClubProject measures 80 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Micromouse Gen1 ClubProject?

105 components, from 37 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 Micromouse Gen1 ClubProject design files?

From the kevinyan0620/Micromouse_Gen1_ClubProject 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 Micromouse Gen1 ClubProject design in my own project?

The repository has no license, so all rights stay with kevinyan0620. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Micromouse Gen1 ClubProject 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.
