The Crowduino is Arduino compatible board. Based on Arduino Duemilanove Schematic, 100% compatible to its existing program, shield and IDEs.
This Crowduino is a microcontroller board based on the ATmega328 (
datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, a reset button, and a XBee socket. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The difference between Crowduino and other arduino compatible is the Crowduino contains a XBee socket . This feature make Crowduino not only adapts to all the shield that compatible with arduino Uno, but also adapts to the
Xbee modules from Digi, and any module with the same footprint.
