Introduction

 

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’s will not communicate with Xbee’s, so RFbee’s need to be used on both ends of the wireless connection.

Application Ideas

 

  • Powerful RF control
  • Easy to implement of WSN (Wireless Sensor Network)
