STMicroelectronics STLINK-V3PWR SMU & Debugger/Programmer for STM32

STMicroelectronics STLINK-V3PWR Source Measurement Unit (SMU) and Debugger/Programmer for STM32 is designed to synchronize code execution with real-time power consumption in STM32 applications. The STMicroelectronics STLINK-V3PWR SMU is ideal for power optimization and can function independently as an SMU, providing power and measuring the target application's current. The device maintains a stable output voltage during rapid current changes.

The STLINK-V3PWR also serves as a standalone debugger and programmer for STM32 microcontrollers. The SMU features a multipath bridge interface with an integrated level shifter for I/O voltage adaptation. Its USB Type-C™ connector supports data communication with a host PC and supplies up to 5V/3A to the probe and the target application. Firmware updates are available via the ST-LINK tool (STSW-LINK007).
