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. https://elecena.pl/product/17496855/b-stlink-isol-isolation-and-voltage-adapter-board-for-stlink-v3set 2021-04-05 https://elecena.pl/product/17496855/b-stlink-isol-isolation-and-voltage-adapter-board-for-stlink-v3set 2021-05-18 https://elecena.pl/product/17496855/b-stlink-isol-isolation-and-voltage-adapter-board-for-stlink-v3set 2022-06-10 https://elecena.pl/product/17496855/b-stlink-isol-isolation-and-voltage-adapter-board-for-stlink-v3set 2022-06-23 https://elecena.pl/product/17496855/b-stlink-isol-isolation-and-voltage-adapter-board-for-stlink-v3set 2023-07-16 https://elecena.pl/product/17496855/b-stlink-isol-isolation-and-voltage-adapter-board-for-stlink-v3set 2025-04-12 https://elecena.pl/product/17496855/b-stlink-isol-isolation-and-voltage-adapter-board-for-stlink-v3set 2025-11-05
