Description

The MYD-LPC185X development board is an evaluation platform for NXP LPC1850 and LPC1857 ARM Cortex-M3 based microcontrollers which include up 200 kB on-chip SRAM and can work at up to 180 MHz. The MYD-LPC185X board takes full features of the ARM Cortex-M3 microcontrollers and exposes many peripheral interfaces 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-LPC185X board may carry one of the two processors (NXP LPC1850 and LPC1857) as to make corresponding models:

MYD-LPC1850 Development Board (based on NXP LPC1850)

MYD-LPC1857 Development Board (based on NXP LPC1857)


The MYD-LPC185X board is provided with plenty of MDK-ARM source code and detailed document as well as some necessary cable accessories to help users evaluate, learning and make prototype base on NXP LPC1850 or LPC1857 ARM Cortex-M3 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.
