Overview Send an Inquiry

The MYD-LPC1857 development board is among the MYD-LPC185X series designed using NXP LPC1857 32-bit ARM Cortex-M3 based microcontroller for embedded applications which includes up to 136kB of on-chip SRAM, a quad SPI Flash Interface (SPIFI), a State Configurable Timer (SCT) subsystem, two High-speed USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals. The LPC1857 operates at CPU frequencies of up to 180 MHz.


The MYD-LPC1857 board takes full features of the NXP LPC1857 ARM microcontroller 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-LPC1857 board comes with sample codes bundle for the peripherals using Keil's MDK-ARM to help users evaluate the NXP LPC1857 ARM Cortex-M3 microcontroller and detailed document as well as some necessary cable accessories to help users evaluate, learning and make prototype 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.
