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