STLINK-V3MODS and STLINK-V3MINI debugger/programmer
tiny probes for STM32 microcontrollers
Introduction
STLINK-V3MODS and STLINK-V3MINI are stand-alone debugging and programming tiny
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 communication with any STM32 microcontroller located on an
application board.
They provide a Virtual COM port interface allowing the host PC to communicate 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 the 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 an STM32 application-
based with its 2 x 16-pin castellated vias connection, while the STLINK-V3MINI offers
STDC14 connectivity with an included STDC14 to STDC14 flat cable.
