How can a powerful sensor does not have a strong and reliable expansion device. Although Edison has a 500MHz Atom, WiFi, Bluetooth and 70 GIPO, but it still lacks a set of sensors to interact with you.
DFRobot sensor they developed from more than 200 kinds of carefully selected, collected some of the most practical and most players use sensors to let you change a wealth of Edison's work. DFRobot sensor kit contains an extended version V7, only incidental Xbee jack, Bluetooth / APC220 interface, an external power port, and 3Pin colored pin to ensure proper wiring. Adding sensors on the extended version V7 is like building blocks are generally simple. With each sensor module sample tutorial, so make more easily.
