STM32F103C8T6 Development Board

This is a scaled-down version of the LCSC STM32F103C8T6 development board (height reduced from 900mil to 800mil, and changed to half-hole design), designed to save space on a row of breadboard holes.
The component positions, except for the header pins, are largely the same as the original, but the PCB routing has been completely redesigned (for practice), and the silkscreen placement and format have also been adjusted. The

show the white square on the back reserved for a QR code (select "Add QR code at specified location during board fabrication," size 6x6mm), which can be deleted if not needed.
Do not select half-hole design during board fabrication (otherwise, there will be a charge). The final board will have copper shavings from the half-hole area, but this does not affect use (you can fill the half-hole with solder when soldering the header pins).
