The LPC4350-DB1, LPC4357-DB1 and LPC1850-DB1 development boards differs by the assembled microcontroller. All other features are the same.

The basic modification of the development board contains:

• The NXP LPC series microcontroller (LPC4350-FET256, LPC4357-FET256 or LPC1850-FET256)
• High-speed USB 2.0 Host/Device/OTG interface (with USB mini-B connector)
• 10/100 Ethernet Port with on-board PHY
• 16MBit on-board NOR Flash
• 20-pin ARM standard JTAG connector
• 4 user push buttons, RESET button and 4 LEDs
• Boot select jumpers

The development boards have soldering options for the following components:

• External SDRAM (the 64 Mbit SDRAM is assembled at LPCXXXX-DB1-B and LPCXXXX-DB1-C board modifications)
• Real-Time Clock (RTC) crystal and power supply
• 10-pin 1.27mm (0.05 inch) Cortex Debug Connector
• 20-pin 1.27mm (0.05 inch) Cortex Debug + ETM Connector

The functionality of the development board can be broaden with a wide range of extension boards:

	LCD-EB-1 3.5 inch TFT Touch Screen LCD Extension Board
	HDMI/DVI Extension Board
	RS232, RS485, CAN Bus and Full Speed USB Extension Board
	SDIO/SD Card + I2C/SPI Memories Extension Board
