8.4

ST-LINK debug connector CN8

The ST-LINK debug connector is a 1x4-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.
