STMicroelectronics STLINK V3 Compact In-circuit Debugger And Programmer For STM32

The STMicroelectronics Mini debugger and programmer for STM32 microcontrollers. It also provides a Virtual COM port interface enabling the host PC to communicate with the target microcontroller through one UART and bridge interfaces such as SPI, I2C, CAN, and GPIOs simplifying, for instance, the field programming through the bootloader.

Self powered through a USB Micro-B connector
USB 2.0 high speed compatible interface
5 V source output capability up to 200 mA
Drag and drop flash programming
Two color LEDs for communication and power
