STM32F103: common questions

What microcontroller does the STM32F103 use?

The STM32F103 is built around the STM32F103CBTx, from the STM32 family.

How big is the STM32F103 PCB?

The STM32F103 measures 42.7 × 34.5 mm, has 2 copper layers and is 0.29 mm thick.

How many components are on the STM32F103?

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

Where can I download the STM32F103 design files?

From the cristobalcuevas/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 STM32F103 design in my own project?

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

Can I test firmware for the STM32F103 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.
