ST B-STLINK-ISOL

The B-STLINK-ISOL board is an add-on module for the STLINK-V3SET, providing galvanic isolation and voltage adaptation for STM32 microcontroller targets operating from 3.3V down to 1.65V. The module can be fitted directly into the original STLINK-V3SET enclosure (when used as an STM32 debug probe via the STDC14 connector for JTAG/SWD/SWV/VCP), or inserted between the STLINK-V3SET motherboard MB1441 and its adapter board MB1440 (when providing bridge signals and access to other connectors). The module does not support STM8 targets, and its voltage adaptation is performed on the baseline adapter board MB1440 provided with the STLINK-V3SET.

• Voltage adaptation and galvanic isolation board for STLINK-V3SET, supporting 1.65V–3.3V
• 2.5kVrms isolation rating; 300Vrms basic isolation working voltage per IEC62368-1:2014
• I/O isolation and level shifting for STM32 debug SWD, SWV, and JTAG signals
• I/O isolation and level shifting for VCP virtual COM port UART signals
• I/O isolation and level shifting for bridged SPI/UART/I2C/CAN/GPIOs signals
• Enclosed housing when using STDC14 connector (for STM32 SWD, SWV, and VCP)
• Compatible connection with STLINK-V3SET adapter board MB1440 (for STM32 MCU JTAG and bridging)

• Debugging for STM32 microcontrollers (JTAG/SWD/SWV/VCP)
• Bridge signal (SPI/UART/I2C/CAN/GPIOs) access for STM32 microcontrollers
