Introduction
BlueBoard Base is modular approach to the ever evolving design of our flagship product
Blueboard-LPC2148. It is designed keeping in mind the requirements of a development engineer,
who could be working on different controllers but would prefer the same peripheral interface or a
company working on different products using different controller and would not prefer to invest
huge amount in individual boards or a hobby enthusiast who would be trying out different
controllers but would not be willing to invest in different boards for each controller. For all these,
the user can buy the required stamp module and work on this board.
Features
BlueBoard Base has various peripherals with configurable jumpers. Extension headers for all
microcontroller pins.
(1) Note: The functionality of the features mentioned for the BlueBoard Base in this document are
direcly dependent on the Stamp board(microcontroller) used. Ex: Using LPC2148 Stamp board all the
features mentioned here are available. But if LPC1114 Stamp Board is used some features like USB,
VGA, etc., are may not be available. This document is for the Blueboard Base + LPC2148 stamp.
