Detail DFRduino Leonardo with Xbee Socket DFRobot Leonardo like Arduino Leonardo
Based on the "Arduino Leonardo", this one from DFRobot equips an XBee socket and 3 sensor extension pins for your application. The Xbee is a commonly used wireless communication module with 2.4G Zigbee,900Mhz version, and etc. The socket makes it possible for you to extend the XBee or XBee form factor wifi, Bluetooth and RF modules for your Arduino directly. However, the D14~D16 extension pins with power supply maximize the use of your ATmega32u4 microcontroller. They support the digital sensors and module from DFRobot directly.
