The small probe is used to upload and debug applications on STM32 MCUs. It uses ST’s 14-pin STDC14 debug cable to provide enhanced features such as Virtual COM Port (VCP). VCP helps observe runtime data on a host PC for quicker, clearer debugging.
STLINK-V3MINI also supports mass storage support for uploading of files directly through the probe. It is drag and drop and allows the trial of new ideas and the running of demo applications. The probe comes with reference files for 3D printing that allow the creation of customised casings for the probe.
STLINK-V3MINI works with the STM32CubeProgrammer and is directly supported in commercial IDEs including Keil MDK-ARM, IAR EWARM, and GCC-based IDEs including STM32CubeIDE. Free access is given to the probe’s low-level APIs to integrate STLINK-V3MINI in custom test platforms.
