ST-LINK debug connector

The ST-LINK debug connector is a 6-pin, 2.54 mm pitch male connector. It provides access to the embedded
SWJ-DP interface of the STM32F103CBT6 MCU. This SWJ-DP interface is a combined JTAG and serial wire
debug port that enables either a serial wire debug or a JTAG probe, to be connected to the target.
