Micromouse v2: common questions

What microcontroller does the Micromouse v2 use?

The Micromouse v2 is built around the STM32F103C8Tx, from the STM32 family.

How big is the Micromouse v2 PCB?

The Micromouse v2 measures 100 × 130 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Micromouse v2?

74 components, from 47 distinct parts. The full bill of materials is listed on this page.

Where can I download the Micromouse v2 design files?

From the minindupasan/micromouse-v2 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 v2 design in my own project?

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

Can I test firmware for the Micromouse v2 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.
