Tiny standalone probe with a USB-C port

29 June 2022 DSP, Micros & Memory

STLINK-V3MINIE from STMicroelectronics is one in the family of in-circuit debuggers/programmers for STM32 microcontrollers and is the newest model and the first to include a USB-C port. STLINK-V3MINIE provides a virtual COM port interface for the host PC to communicate with the target microcontroller through one UART. The USB-C port provides power to STLINK-V3MINIE as well as allowing communication between the microcontroller and host PC.

At 15 x 42 mm it is slightly longer than the STLINK-V3MODS programmer. It also stands out thanks to its support for low-power microcontrollers and as such, is the first standalone probe compatible with the latest STLINK to support 1,65 V. Developers working on a 1,8 V application no longer need to use the STLINK-V3SET and one of its expansion cards.

Its small size primarily targets developers that must constantly flash firmware in the field. As a result, it supports SWD, SWV, and VCP thanks to its STDC14 connector. However, due to its size, the STLINK-V3MINIE does not supply power to the embedded system.
