This microcontroller board can wirelessly connect to an XBee radio (sold separately). It comes with 22 I/O pins (14 digital, 8 analog) and a Mini-USB port for charging. Built on the 'open-source electronics prototyping platform', and compatible with existing Arduino software lilbraries.

• 8-bit AVR RISC-based microcontroller running at 8 MHz
• On/off slide switch
• Charging circuit for lithium polymer battery
• Connector for interfacing with XBee modules
• Flexible power source (USB or lithium polymer battery)
• Compatible with existing Arduino software libraries
