MircoMouse: common questions

What microcontroller does the MircoMouse use?

The MircoMouse is built around the STM32WB55RGV6, from the STM32 family.

How big is the MircoMouse PCB?

The MircoMouse measures 50 × 50 mm, has 8 copper layers and is 1.6 mm thick.

How many components are on the MircoMouse?

77 components, from 35 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 MircoMouse design files?

From the Karanami/MircoMouse 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 MircoMouse design in my own project?

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

Can I test firmware for the MircoMouse 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.
