B-STLINK-VOLT

Description

The B-STLINK-VOLT board is an additional module for the STLINK-V3SET,
performing voltage adaptation for STM32 microcontroller targets running below 3.3 V
down to 1.65 V.

This module can be enclosed directly in the original STLINK-V3SET casing when
used as an STM32 debugging probe (JTAG/SWD/SWV/VCP) through the STDC14
connector. It can be inserted also between the STLINK-V3SET main board (MB1441)
and its baseline adapter board (MB1440) when providing access to bridge signals
and other connectors.

B-STLINK-VOLT is not required for STM8 targets, for which voltage adaptation is
performed on the baseline adapter board (MB1440) provided with the STLINK­V3SET.
