9.1 Conventions
Per conventions, refer to T
able 15 for the I/O type definition:
Table 15. I/O type definition
Type Definition
I Signal is an input for STLINK-V3PWR and an output for the target application
O Signal is an output for STLINK-V3PWR and an input for the target application
I/O Bidirectional signal or can be configured as input or output (default input)
S Supply pin
9.2 POWER (OUT/AUX)
The POWER connector (Figure 10) is a 3‑pin screw terminal block with a 5.00 mm pitch. It is used to supply a
target application using cables.

Name Type Description
OUT S SMU output (refer to Section 7.2)
GND S Ground
AUX S Auxiliary power source output (refer to Section 7.3)
9.3 DEBUG (STM32 JTAG/SWD and VCP)
The DEBUG (STDC14) connector in Figure 1
1 is a 2x7‑pin with a 1.27 mm pitch. It allows connection to an
STM32 target using the JTAG or SWD protocol, respecting (from pin 3 to pin 12) the MIPI10/ARM10 pinout (Arm
®
Cortex
®
debug connector).
It also provides two UART signals for the Virtual COM port. The related pinout for the DEBUG connector is listed
in Table 17.
