STLINK-V3PWR is a two-in-one standalone debugger probe and a source measurement unit (SMU) designed to synchronize code execution with a power consumption of STM32 applications in real time. This tool is specifically adapted for power consumption optimization (patent pending). STLINK-V3PWR can be used as a standalone source measurement unit to supply power and measure the current consumption of the target application. The product keeps the output voltage constant during a fast current transient from a very low current to a high current. STLINK-V3PWR is also a standalone debugging and programming probe for STM32 microcontrollers. The product embeds a multipath bridge interface with an integrated level shifter to adapt to the target application I/Os voltage. STLINK-V3PWR USB Type-C® connector allows data communication with the host PC and sinks up to 5 V/3 A to supply both the probe and the target application, via the SMU and the auxiliary output. The ST-LINK firmware upgrade tool (STSW-LINK007) can update the STLINK-V3PWR firmware. For optimal performance, the STLINK-V3PWR firmware must be updated to the latest version. https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2023-03-21 https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2023-07-17 https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2023-11-17 https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2025-06-11 https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2025-06-30 https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2025-11-13 https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2026-03-24 https://elecena.pl/product/22991092/stlink-v3pwr-stlink-v3-compact-in-circuit-debugger-and-programmer-for-stm32 2026-04-02
