README.mdstm32-PCB-design
PCB board for STM32F103C8T6 Microcontroller, a micro usb power supply, a regulator to power the mcu to 3.3V, and a crystal oscillator for the mcu. It has a reset switch to boot the board, a UART interface UART (Universal Asynchronous Receiver-Transmitter) to uses two wires to exchange serial data between devices without a shared clock, as well as Serial Wire Debug (SWD) which is a hardware interface designed by ARM for programming and debugging ARM-based microcontrollers using a st-link programmer.

Questions
How big is the Stm32-PCB design PCB?
It measures 44.2 × 31.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32-PCB design use?
32 parts, built around the STM32F103C8T6 and AMS1117. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Stm32-PCB design KiCad files?
From the hughmancoder/stm32-PCB-design repository on GitHub, at the commit this page was made from: the board is stm32 PCB design.kicad_pcb and its schematic .kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32-PCB design design in my own project?
Its repository states no licence, so its author keeps all rights: ask hughmancoder before reusing the design.
