MicroMouse: common questions

What microcontroller does the MicroMouse use?

The MicroMouse is built around the STM32F103C8T6, from the STM32 family.

How big is the MicroMouse PCB?

The MicroMouse measures 43 × 38 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MicroMouse?

28 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the MicroMouse design files?

From the Sanjula-23/Custom-PCB-Designing repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MicroMouse design in my own project?

The repository has no license, so all rights stay with Sanjula-23. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MicroMouse 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.
