From the project
Three custom boards designed in KiCad for Falali. Each folder contains the KiCad sources (.kicadsch / .kicadpcb / .kicadpro), the netlist (.net, ground truth for pinout), schematic/layout renders, and a fab-output/` folder with the Gerbers + drill files sent to fabrication.

Wheel Drive: common questions
What microcontroller does the Wheel Drive use?
The Wheel Drive is built around the ESP32-S3-DevKitC, from the ESP32 family.
How big is the Wheel Drive PCB?
The Wheel Drive measures 130 × 105 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Wheel Drive?
24 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Wheel Drive design files?
From the chuahengli/30.007-Engineering-Design-Innovation-Falali-AMR repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Wheel Drive design in my own project?
The repository has no license, so all rights stay with chuahengli. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Wheel Drive without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
