RFbee V1.1 - Wireless arduino compatible node - Seeed Studio

The RFBee is a RF module providing easy and flexible wireless data transmission between devices. It is based on a AVR Atmega168 working as a fully functional Arduino connected via SPI to a TI CC1101 RF transceiver.
Features
Range: indoor/Urban: up to 50m; Outdoor line-of-sight: up to 120m;
Receiver sensitivity: -95dBm
RF data transmission rate: 4,800bps; 76,800bps
Working frequency : 868MHz & 915MHz
Communication type: Point to Point, or Point to Multipoint.
Easy-to-Use serial interface and rich extendable ports
Easy-to-Use AT command: Set working mode, Serial Baud Rate, etc.
Open source hardware and firmware
Socket compatible with the Xbee, so you can plug it into any Xbee socket as a quick replacement.
Note
only the Rx,Tx, VCC, GND pins are identical to the Xbee. RFbee will not communicate with Xbee, so RFbee need to be used on both ends of the wireless connection.
