Description
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,
I
2
C, 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.
