LPC1769 LPCXpresso Board

NOTE: This product is now obsolete. A replacement is available: LPC1769 LPCXpresso with CMSIS-DAP.


The LPC1769 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. The LPCXpresso comprises a target board combined with a JTAG debugger. A free Eclipse-based IDE from NXP is also included.

The LPC1769 has 64 kB SRAM, 512 kB Flash, 4xUART, 3xI2C, SPI, 2xSSP, 2xCAN, PWM, USB 2.0 Device/Host/OTG, RTC, Ethernet, I2S, etc. Embedded Artists also provides a Prototype board and a Base board that makes it possible to make experiments and prototyping with many peripherals.

LPCXpresso Kit

The LPCXpresso Kit (EA-XPR-103) is a bundle containing the LPC1769 LPCXpresso Board (EA-XPR-003) and the LPCXpresso Base Board (EA-XPR-021).

Recommended Book

Embedded Artists recommends Richard Barry's book "Using the FreeRTOS Real Time Kernel - a Practical Guide", which includes sixteen examples written specifically for the LPC17xx Cortex M3. This is a concise, step by step, 'hands on' guide that describes both general multitasking concepts and FreeRTOS specifics. The book is purchased here.
