Waveshare STLINK-V3MINIE In-Circuit Debugger and Programmer Board for STM32

STLINK-V3MINIE is a tiny stand-alone probe for debugging and programming STM32 microcontrollers, portable and easy to use. The built-in JTAG/SWD interfaces for communicating with the STM32 microcontroller also provide a virtual COM port for the host PC to communicate with the target microcontroller via a UART.
Characteristics:
1. Small 15mm x 42mm stand-alone programming and debugging probe for STM32 microcontrollers
2. Self-powered via a USB Type-C connector
3. High-speed USB 2.0 interface
4. The probe firmware is upgradeable via USB
5. Support drag-and-drop Flash programming of binary files
6. Dual-color LED: communication, power
7. Support JTAG communication up to 21MHz
8. Support SWD (Serial Wire Debug) and SWV (Serial Wire Viewer) communication up to 24 MHz
9. Virtual COM Port (VCP) up to 15 Mbps
10. Support application voltage from 1.65 to 3.60V
