The STLINK-V3MODS is a small size debugging and programming probe for STM32 microcontrollers.
The JTAG/SWD interfaces are used to communicate with any STM32 microcontroller located on an application board.
The STLINK-V3MODS also provides a Virtual COM port interface enabling the host PC to communicate with the target microcontroller through one UART, and bridge interfaces (SPI, I2C, CAN, GPIOs) simplifying for instance the field programming through bootloader.
The STLINK-V3MODS is ready to be embedded in a master application and can be directly soldered on the PCB motherboard.Key Features
