Data brief
Features
STMicroelectronics® patented advanced
current control
Fully autonomous solution embedding an
STM32™ MCU and the L6472 stepper motor
driver
Compatible with SPIN family evaluation
software
Wide voltage range from 8 V to 45 V
High phase current up to 3 Ar.m.s
Footprint for external resonator or crystal
Switch motor input control
Keys start/left - stop/right - reset
Ready, busy, error LED indicators
Spare LED indicators for specific design
Adjustable supply voltage compensation
Up to 1/16 microstepping
Description
The L6472 Discovery is a low cost development
tool to explore the L6472 motor driver.
An ideal starter-kit for both beginners and
experienced users, it is autonomous and can be
used with a software interface or with a custom
firmware thanks to the embedded microcontroller.
Through the available GUI the user can easily set
the full configuration of application parameters.
“Plug and Play” tool it offers high motor control
flexibility thanks to the wide operating voltage
range from 8 V to 45 V and the current capability
up to 3 Ar.m.s. It is equipped with LED indicators
for specific ready, busy, error warning.
