From the project

STM32 based development board design using KiCAD

This project contains KiCAD project files for a custom STM32 development board PCB which uses the STM32F103C8Tx microcontroller.

The development board uses the STM32F103C8Tx microcontroller. USB interface is used for both power supply and serial communication. The power fdrom the USB interface is regulated to +3.3V using the regulator circuit. An High Speed External clock is used for 16 MHz operation. The board includes pin header ports for UART and I2C communication also.

Stm32-devboard: common questions

What microcontroller does the Stm32-devboard use?

The Stm32-devboard is built around the STM32F103C8Tx, from the STM32 family.

How big is the Stm32-devboard PCB?

The Stm32-devboard measures 37 × 32.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32-devboard?

28 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stm32-devboard design files?

From the devnithw/stm32-devboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Stm32-devboard design in my own project?

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

Can I test firmware for the Stm32-devboard 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.
