Product Information
Item Name: 
RFD900A Telemetry Radio Set Telemetry for Long Distance Data Transmission

Feature:

- RFD900A is a 32-bit processor that supports higher baud rates and airspeeds
- Wireless data transmission module with small size and excellent performance
- No distinction is made between transmitter and receiver modules. Each module integrates a USB serial port chip, the USB and UART interfaces are automatically switched, and the USB is preferred
- Operating frequency range 902-928MHz, ISM band
- The transmitting circuit adopts a low-noise amplifier greater than 20DB, and a low-pass filtering unit
- The transmit power is adjustable and the maximum transmit power is 1W
- High-sensitivity LNA and SAW circuit in front of the receiving circuit
- The outdoor communication distance can be up to 40km or more in a straight line (depending on the antenna performance and communication speed requirements)
- Over-the-air data rates up to 250Kbps
- Dual antenna interface, support antenna diversity, differentiated antenna configuration
- Support AT command configuration of local radio, RT command configuration of remote radio
- With module temperature monitoring function, automatic duty cycle adjustment according to temperature to avoid module over-temperature
- Working temperature -40â to +85â
- Dimensions: 33 x 53 x 9.6mm/1.3 x 2.1 x 0.4"
- Weight: 23G/0.05LB
