LPCXpresso Base Board

The LPCXpresso Base board makes it possible for you to get started with experiments and prototyping immediately. The Base board can also be used together with the mbed module. More information about mbed can be found at mbed

It is possible to buy the Base board combined with the LPCXpresso board. The LPCXpresso kit reduces the price with 7 EUR compared to if you buy the parts separately.

Kits

This Base Board can be bought in a kit together with a LPCXpresso LPC1xxx board for a discounted price.

Specification
