Guide: Connecting your debugger

Connecting Via SWD HeaderConnecting to JTAG HeaderConnecting to GPIO PinsThe easiest way to connect your development board to your debugger is by using the 4-pin SWD header, if present. This header is usually a male dupont header, but female headers are also used. The header exposes a ground pin, a +3.3V pin, a clock pin, and a data pin. Note: There is no particular order in which these pins are arranged. Warning: See more on stm32-base STM32World Wiki
