STLINK-V3MODS and STLINK-V3MINI

mini debuggers/programmers for STM32

Introduction

The STLINK-V3MODS and STLINK-V3MINI are stand-alone debugging and programming

mini probes for STM32 microcontrollers. These products are designed in a very low form

factor and both offer high performance without any compromise to functions. They support

the JTAG/SWD interfaces for the communication with any STM32 microcontroller located on

an application board.

They provide a Virtual COM port interface allowing the host PC to communication with the

target microcontroller through one UART. The STLINK-V3MODS also provides bridge

interfaces to several communication protocols allowing for instance the programming of the

target through bootloader.

The STLINK-V3MODS and STLINK-V3MINI are both proposed for different uses. The

STLINK-V3MODS may be directly soldered on a host PCB including a STM32 application-

based with its 2 x16-pin castellated vias connection, while the STLINK-V3MINI offers

STDC14 connectivity with an included STDC14 to STDC14 flat cable.
