Figure 9 shows how to connect the ST-LINK/V2 to a target using the JTAG cable.

Figure 9. JTAG and SWD connection

1. A = Target application board with JTAG connector

2. B = JTAG/SWD 20-wire flat cable

3. C= STM32 JTAG and SWD target connector

The reference of the connector needed on the target application board is:

2x10C header wrapping 2x40C H3/9.5 (pitch 2.54) - HED20 SCOTT PHSD80.

Note:

For low cost applications or when the standard 20-pin 2.54mm-pitch connector footprint is

too big, it is possible to implement the Tag-Connect solution to save cost and space on the

application board. The Tag-Connect adapter and cable provide a simple and reliable means

of connecting ST-LINK/V2 or ST-LINK/V2-ISOL to the PCB without requiring a mating

component on the application PCB.
