X-NUCLEO-IHM15A1 - STMICROELECTRONICS

Features

•Voltage range from 7 to 45 V

• Output current up to 1.5 Arms for each motor

• Two independent current limiters with adjustable OFF time

• Full protection set including: overcurrent, short-circuit, under voltage lock out

and thermal shutdown

• Parallel operation

• Compatible with Arduino UNO R3 connector

• Compatible with STM32 Nucleo boards

Description

The X-NUCLEO-IHM15A1 dual brush DC motor driver expansion board is based on

the STSPIN840 for STM32 Nucleo.

It provides an affordable and easy-to-use solution for the implementation of compact

motor driving applications such as thermal printers, robotics and toys.

Thanks to the parallel operation, it can be easily converted to a single brush DC

driver with double current capability.

The current limiters and complete set of protection features make it suitable for

rugged applications.

The X-NUCLEO-IHM15A1 is compatible with the Arduino UNO R3 connector and

most STM32 Nucleo boards.
