LPC1549 LPCXpresso Board

The LPC1549 LPCXpresso board with NXP's ARM Cortex-M3 microcontroller has been designed to make it as easy as possible to get started with Cortex-M3.

An LPCXpresso board consists of a target side (LPC1549, in this case) and a build-in LPC-Link2 debug probe, which is compatible with the free LPCXpresso IDE out-of-the-box, and with other toolchains via optional ARM CMSIS-DAP and Segger J-Link firmware.

The LPC1549 has 36 kB SRAM, 256 kB Flash, 4 kB E2PROM, 3xUART, I2C, 2xSPI/SSP, CAN, PWM, USB 2.0 Device, RTC, etc.

LPCXpresso V2

Since the introduction of the first variant in 2009, the original LPCXpresso board has reenergised the whole MCU evaluation board market. Embedded Artists and NXP are now proud to introduce the new generation of LPCXpresso V2 boards which build upon the original design, providing many new and exciting features.


The LPCOpen Platform allows users to quickly and easily utilize NXP's extensive array of microcontroller software libraries to create and develop multifunctional products. The platform uses common APIs that work equally across all microcontroller families and can be built with Keil, IAR, and LPCXpresso (Eclipse-based tool) tool chains.

mbed SDK

The LPC1549 LPCXpresso is supported by the mbed framework.
