Voiture: common questions

What microcontroller does the Voiture use?

The Voiture is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Voiture PCB?

The Voiture measures 110 × 103.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Voiture?

70 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Voiture design files?

From the KimotoHoitsu/Voiture-guidee-par-main repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Voiture design in my own project?

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

Can I test firmware for the Voiture 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.
