From the project

A super nice projet

L'objectif de ce projet est de reconstituer un simulateur de voiture permettant de ressentir les vraies sensations de conduite, avec un frein à retour de force et 4 pieds movibles.

On s'inspire du projet : https://github.com/ChrGri/DIY-Sim-Racing-FFB-Pedal

La base ayant déjà été faite, on souhaite modifier le châssis et les pédales de frein afin d'augmenter la sensation de conduire une véritable voiture.

The KiCad project lives in the MOAalpha/2425_Projet1AB_SIMU4DX repository on GitHub; these links point at the commit this page was built from.

Motor driver: common questions

What microcontroller does the Motor driver use?

The Motor driver is built around the STM32L412KBTx, from the STM32 family.

How big is the Motor driver PCB?

The Motor driver measures 80 × 92.3 mm, has 4 copper layers and is 1.564 mm thick.

How many components are on the Motor driver?

83 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Motor driver design files?

From the MOAalpha/2425_Projet1AB_SIMU4DX repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Motor driver design in my own project?

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

Can I test firmware for the Motor driver 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.
