STM32F103-dev board: common questions
What microcontroller does the STM32F103-dev board use?
The STM32F103-dev board is built around the STM32F103C8T6, from the STM32 family.
How big is the STM32F103-dev board?
The STM32F103-dev board measures 38 × 38 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the STM32F103-dev board?
21 components, from 11 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 STM32F103-dev board design files?
From the Kraad25/STM32F103-dev-board 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 STM32F103-dev board design in my own project?
The repository has no license, so all rights stay with Kraad25. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the STM32F103-dev 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.
