Overview

The ST-LINK/V3MODS is a modular in-circuit debugger and programmer for STM32 microcontrollers, designed as a small-form-factor board that can be soldered directly onto a carrier PCB. It supports high-speed USB 2.0 communication and provides a versatile bridge interface for communicating with the target via SPI, I2C, CAN, and UART.

Why Choose This Part

This module supports high-speed USB 2.0 for faster code uploads and features a modular design with 1.27 mm pitch castellated vias for easy PCB integration. It offers broad voltage compatibility from 3V to 3.6V and provides 5V tolerant I/Os, making it robust for various STM32 hardware environments.

Applications

Production Line Programming
The castellated via design allows the module to be soldered directly onto production fixtures for automated flashing.
Integrated Development
Embedding the debugger directly into a custom development board to provide plug-and-play USB debugging for end users.
Protocol Bridging
Using the virtual COM port and bridge interfaces to communicate between a PC and a target system via SPI, CAN, or I2C.
