Description

The B-STLINK-ISOL board is an additional module for STLINK-V3SET, performing

galvanic isolation and voltage adaptation for STM32 microcontroller targets running

below 3.3 V down to 1.65 V.

The 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 also inserted between the STLINK-V3SET main board (MB1441)

and its adapter board (MB1440) when providing access to bridge signals and other

connectors.

B-STLINK-ISOL does not support STM8 targets, for which voltage adaptation is

performed on the baseline adapter board (MB1440) provided with the STLINK-

V3SET.
