Blueboard originates from some concepts on transfering & pre-processing sensing data over Bluetooth. It is pin compatible with Pro Mini 328 (3.3V/8MHz ATmega328 Arduino). It has ADXL335 and Roving Networks Bluetooth module RN41/42 that can be enabled/disabled on the board. The footprints are for 0603 parts and physically it is of size between Arduino Pro Mini and standard Due/Uno (use 3.3 FTDI Breakout Board to upload code). v1.1 is a smaller variant with just mega328 and Bluetooth module. v2 (the smallest one) is using all in one Nordic SoC which is M4+BLE.
