Open1788 Standard Lpc Development Board Lpc1788fbd208 MCU

Overview

Open1788 is an LPC development board designed for the LPC1788FBD208 microcontroller, consists of the mother board and the MCU core board Core1788.

The Open1788 supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with NXP LPC series microcontrollers.
