1. Introduction

The LPCXpresso-MAX family of boards provides a powerful and flexible development 
system for NXP's low end Cortex-M0+ MCUs. They can be used with a range of 
development tools, including the MCUXpresso IDE toolchain. The LPCXpresso845MAX 
board is developed by NXP to enable evaluation of and prototyping with the LPC84x 
family of MCUs. 

Figure 1

 shows the LPCXpresso845MAX Board.

 

The LPCXpresso845MAX board includes the following features:

Compatible with MCUXpresso IDE and other popular toolchains (incl. IAR and Keil).

On-board CMSIS-DAP (debug probe) with VCOM port, based on LPC11U35 MCU.

Debug connector to allow debug of target MCU using an external probe.

Red, Green and Blue User LEDs.

Target ISP and User/Wake buttons.

Target Reset button.

LPCXpresso expansion connector.

DAC output via speaker driver and speaker.

Arduino connectors compatible with the “Arduino UNO” platform.

Pmod® compatible expansion header.

Prototyping area.
