PCBMints2025: common questions
What microcontroller does the PCBMints2025 use?
The PCBMints2025 is built around the STM32G031C8U6, from the STM32 family.
How big is the PCBMints2025 PCB?
The PCBMints2025 measures 80 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the PCBMints2025?
50 components, from 42 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the PCBMints2025 design files?
From the mi3nts/PCBMints2025 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the PCBMints2025 design in my own project?
Yes, under the terms of its MIT license, which mi3nts chose for the repository.
Can I test firmware for the PCBMints2025 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.
