B-STLINK-ISOL
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 STLINKV3SET.
