Description

The MYD-LPC435X series development boards are designed based on NXP LPC4350 and LPC4357 ARM Cotex-M4 and Cortex-M0 asymmetrical dual-core processors which bring the advantage of developing DSP and MCU applications within a single architecture and development environment and can work at up to 204MHz. The MYD-LPC435X board takes full features of the two NXP ARM processors and has rich peripherals including 3 UARTs, USB Host, OTG, Ethernet, 2 CAN interfaces, RS485, LCD, Audio, etc. It has 32MB SDRAM, 2MB Nor Flash and 4MB Data Flash as well as one Micro SD card slot to enhance storage capabilities.

The MYD-LPC435X board may carry one of the two processors (NXP LPC4350 and LPC4357) as to make corresponding models:

MYD-LPC4350 Development Board (based on NXP LPC4350) 
MYD-LPC4357 Development Board (based on NXP LPC4357)

The MYD-LPC435X board comes with plenty of Keil MDK-ARM source code and detailed document as well as some necessary cable accessories to help users evaluate, learning and make prototype based on NXP LPC4350 or LPC4357 ARM Cortex-M4 processor at a fast period. The board enables customers to develop a wide range of applications such as motor control, power management, industrial automation, robotics, medical, automotive accessories, and embedded audio.
