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. ![enter image description here][1] ![enter image description here][2] 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.
