From the project

Carte électronique pour la Coupe de France de robotique

La carte principale est basée sur une Teensy 4.1, la communication est faite par Wi-Fi via un ESP32 et la communication interne du robot via un bus CAN. Les cartes sont modulaires et spécifiques, on peut ajouter plusieurs fois le meme types de cartes il faut juste changer l'ID CAN de la carte en soft. Le microcontroleur des cartes périphériques est un STM32F302C8T6.

PCB AX12: common questions

What microcontroller does the PCB AX12 use?

The PCB AX12 is built around the STM32F302C6Tx, from the STM32 family.

How big is the PCB AX12?

The PCB AX12 measures 62 × 45.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB AX12?

42 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB AX12 design files?

From the PCBrs/CDR-Electronique repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB AX12 design in my own project?

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

Can I test firmware for the PCB AX12 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.
