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.

Key features
  • 1.65 V - 3.3 V voltage adapter and galvanic isolation board for STLINK-V3SET
  • 2.5 kVrms insulation rating; 300 Vrms basic insulation working voltage per IEC 62368‑1:2014
  • Input/output isolation and level shifters for STM32 debug SWD, SWV, and JTAG signals
  • Input/output isolation and level shifters for VCP Virtual COM port (UART) signals
  • Input/output isolation and level shifters for bridge (SPI/UART/I2C/CAN/GPIOs) signals
  • Closed casing when using the STDC14 connector (STM32 SWD, SWV, and VCP)
  • Connection compatible with the STLINK-V3SET adapter board (MB1440) for STM32 microcontrollers JTAG and bridge
