Bilan: common questions
What microcontroller does the Bilan use?
The Bilan is built around the STM32G431KBTx, from the STM32 family.
How big is the Bilan PCB?
The Bilan measures 94 × 68.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Bilan?
103 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the Bilan design files?
From the AresEnsea/2324_Projet2A_AresCFR repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Bilan design in my own project?
The repository has no license, so all rights stay with AresEnsea. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Bilan 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.
