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 lnpanini/Falali 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 lnpanini. 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.
