Blue pill: common questions

What microcontroller does the Blue pill use?

The Blue pill is built around the STM32F103C8Tx, from the STM32 family.

How big is the Blue pill PCB?

The Blue pill measures 47 × 32.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Blue pill?

32 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Blue pill design files?

From the DasReyxr/STM32F-CAR repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Blue pill design in my own project?

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

Can I test firmware for the Blue pill 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.
