Grove modules are quickly growing in popularity due to each sensor and actuator having the same standardized connector -- making it fast and easy to prototype a sensor project.
In the words of Seeed Studio, "Grove is a modulated, ready-to-use tool set. Much like Lego, it takes a building block approach to assembling electronics. Compared with the traditional, complicated learning method of using a breadboard and various electronic components to assemble a project, Grove simplifies and condenses the learning process significantly. The Grove system consists of a base shield and various modules with standardized connectors.
What makes Grove devices so simple is that the connectors eliminate the need to break out the breadboard, resistors, jumper wires, etc.. The connection is a 4-pin interface that supports digital, analog, I2C signal through four wires with different colors.
Since Digi XBee is used frequently in wireless sensor networks, we included six Grove connectors on the new Digi XBee Grove Development Board. You can use it to quickly evaluate Digi XBee and Grove modules with a PC or micro-controller.
We have included two Digi XBee Grove Adapter Boards in the Wireless Connectivity Kit. If you're interested in how this might help you build wireless sensor networks, we have this graphic that offers an overview of the board and its connections.
