DFR0221 ARDUINO Leonardo with XBEE Socket based on Atmega32u4 chip
Overview
DFRduino Leonardo DFRobot Leonardo with Xbee socket is an Arduino Leonardo variant processor
The Arduino Leonardo is based on the ATmega32u4 chip
It is the latest addition to the Arduino family
Compared with the earlier Arduino controllors,by using the ATmega32U4 as its sole microcontroller, allows the Leonardo to be cheaper and simpler to use
Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol
Based on the Arduino official Leonardo processor,this one from DFRobot equips an xbee socket and 3 sensor extension pins for your application
The Xbee is 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
Note : This board is only supported in the latest Arduino IDE 1.0.1 or later version so you will also need to update the IDE
