The guide is drafted with all 48 pins and practical wiring guidance. I’m checking the remaining source gaps, particularly boot-mode selection and the alternatives’ specifications, so compatibility claims stay clear.
Created the STM32F103C8T6 Application and Usage Guide in the project files, covering all seven requested sections, all 48 pins, practical circuitry, and source citations. Boot-table verification and alternative specifications/lifecycle remain explicitly flagged as unresolved; no other-manufacturer drop-in replacement was verified. The schematic and PCB are unchanged.
