Bluepill board: common questions
What microcontroller does the Bluepill board use?
The Bluepill board is built around the STM32F103C8T6, from the STM32 family.
How big is the Bluepill board?
The Bluepill board measures 41 × 36 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Bluepill board?
28 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the Bluepill board design files?
From the SinaKarvandi/PCB-Designs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Bluepill board design in my own project?
Yes, under the terms of its GPL-3.0 license, which SinaKarvandi chose for the repository.
Can I test firmware for the Bluepill board 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.
