STMicroelectronics B-STLINK-ISOL Isolation & Voltage Adapter Board

STMicroelectronics B-STLINK-ISOL Isolation & Voltage Adapter Board is an additional module for the STLINK-V3SET. It performs galvanic isolation and voltage adaptation for STM32 microcontroller targets running below 3.3V down to 1.65V. The module is enclosed directly in the original STLINK-V3SET casing when used as an STM32 debugging probe (JTAG/SWD/SWV/VCP) through the STDC14 connector. The B-STLINK-ISOL can be inserted between the STLINK-V3SET mainboard (MB1441) and its adapter board (MB1440) when providing access to bridge signals and other connectors.
