2 Introduction
Thank you for buying Embedded Artists’ LPCXpresso Motor Control Kit based on NXP’s motor control
solutions. The board has been developed in close cooperation with NXP. The kit contains an
LPCXpresso board with LPC1114 target, which has a Cortex-M0 core, as motor controller. Several
other NXP MCUs can also be used with the board to demonstrate motor control.
This document is a User’s Guide that describes the combination of the LPCXpresso Motor Control
Board and the LPCXpresso LPC1114, together forming the LPCXpresso Motor Control Kit.
2.1 Features
Embedded Artists’ LPCXpresso Motor Control Kit makes it possible for you to get started with motor
control prototyping immediately. It is a universal platform for low voltage motor control based on NXP’s
MCUs. With this platform it is possible to control BLDC, BLAC, stepper and dual brushed DC motors.
The board has been designed for evaluation and is not designed for final integration into end-products
performing motor control.
