7.3 STLINK-V3SET 

functions

All functions have been designed for high performance: all signals are 3.3-volt compatible 
except the SWIM protocol, which supports a voltage range from 1.65 V to 5.5 V. The 
following description concerns the two boards MB1441 and MB1440 and indicates where to 
find the functions on the boards and connectors. The main module for high performance 
only includes the MB1441 board. The adapter configuration for added functions includes 
both the MB1441 and MB1440 boards.

7.3.1 

SWD with SWV

SWD protocol is a Debug/Program protocol used for STM32 microcontrollers with SWV as a 
trace. The signals are 3.3-volt compatible and can perform up to 24 MHz. This function is 
available on MB1441.CN1 and MB1440.CN1.CN2.CN6
