Stm32g431: common questions
What microcontroller does the Stm32g431 use?
The Stm32g431 is built around the STM32G431KBTx, from the STM32 family.
How big is the Stm32g431 PCB?
The Stm32g431 measures 30 × 26.8 mm, has 4 copper layers and is 1 mm thick.
How many components are on the Stm32g431?
29 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the Stm32g431 design files?
From the cpeniche/hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Stm32g431 design in my own project?
The repository has no license, so all rights stay with cpeniche. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Stm32g431 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.
