Carte moteur: common questions
What microcontroller does the Carte moteur use?
The Carte moteur is built around the STM32G474RETx, from the STM32 family.
How big is the Carte moteur PCB?
The Carte moteur measures 72.6 × 73.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Carte moteur?
119 components, from 36 distinct parts. The full bill of materials is listed on this page.
Where can I download the Carte moteur design files?
From the Pokibot-org/pokibot_elec repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Carte moteur design in my own project?
Yes, under the terms of its Apache-2.0 license, which Pokibot-org chose for the repository.
Can I test firmware for the Carte moteur 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.
