Blueboard is an open-source initiative at realizing cost effective
prototyping and solutions using the versatile LPC 214x series of
microcontrollers. Driven at present, by engineering and support from NGX
Technologies, the board is provided with necessary interfaces for a quick
realization of embedded solutions. NGX Technologies? Blue Board - LPC2148 is a
ready-to-run development platform with code snippets to demonstrate applications
for every feature supported on the board. The Blue Board offers ubiquitous
interfaces making it the best board available for the offered price. All the
technical information related to the project is freely available.
