JeeLab’s Jean-Claude Wippler has been “rethinking the Arduino interface” since 2008, when he first attached an ISM band radio to a Modern Device Real Bare Bones Board. Three and a half years later he has built quite a library of sensors and breakout “plugs” for the JeeLabs Platform. The heart of the platform is the JeeNode (see below), which adds an inexpensive radio to an RBBB-style development board.
All of the pins of the Atmega328 are reorganized into four ports that have the same pinout: IRQ, Analog In, Regulated Power, GND, Digital In, Power In.
Sensor plugs can be small and all have the same interface; most communicate with the microcontroller using I2C (a common on-board option in a lot of sensor ICs). A set of Arduino libraries provides a consistent interface to the sensor plugs and the wireless module.
Jean Claude’s blog is worth setting aside some time…
