From the project

Custom STM32F103C8T6 development board designed in KiCad and hand-assembled as a prototype.

A custom STM32F103C8T6 development board designed in KiCad and taken through the full prototype workflow: schematic capture, PCB layout, manufacturing output generation, PCB fabrication, component sourcing, hand soldering, and physical assembly.

The board was designed as a compact embedded development platform exposing common STM32 interfaces for firmware experiments, peripheral testing, and hardware bring-up practice.
