LPC4357 Evaluation Board:
The board is built around the NXP LPC4357 which delivers a versatile dual-core configuration using an ARM Cortex-M4 MCU with an ARM Cortex-M0 as a co-processor. This is the first ARM Cortex board at this price point to deliver dual-core performance and media interface features including 1MB of dual-bank Flash, high speed USB host and device, an LCD interface, SD card and more.
This development board includes peripherals well-suited for development of multi-media, audio, medical, industrial control and motor control applications and provides ideal rapid prototyping opportunities for hobbyists and game console designers.
The connectors on the LPC4357 evaluation board provide easy access to many of the LPC4357's on-chip peripherals.
