From the project
This is my repo for the first version of full size micromouse development.
A competition-style micromouse robot on a custom 100 × 120 mm, 4-layer KiCad 10 PCB: ESP32-S3 module doing all control + wireless telemetry, a 2S power tree with a regulated 6 V motor rail, a BNO055 9-axis IMU, research- verified sensor geometry, and a fully script-generated, fully autorouted design.

Micromouse pcb simplified-2l: common questions
What microcontroller does the Micromouse pcb simplified-2l use?
The Micromouse pcb simplified-2l is built around the XIAO-nRF52840-Plus-SMD, from the Nordic nRF family.
How big is the Micromouse pcb simplified-2l?
The Micromouse pcb simplified-2l measures 100 × 120 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Micromouse pcb simplified-2l?
63 components, from 31 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 pcb simplified-2l design files?
From the MukeshSethy/micromouse-runner repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Micromouse pcb simplified-2l design in my own project?
The repository has no license, so all rights stay with MukeshSethy. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Micromouse pcb simplified-2l without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
