The LPC4350-DB1, LPC4357-DB1 and LPC1850-DB1 development boards have most of the microcontroller pins available at the side connectors.

You can connect a demoboard to a wide range of extension boards or to your prototyping board.

All demoboards are pin-to-pin compatible. You can easily test the same design with different microcontrollers by replacing one board with another.
