Tarot RFD900A Telemetry Radio RC Plane Telemetry Data Transmission for Pixhawk Flight Controller

Description:
RFD900A is a data transmission module specially designed and developed for model drones over long distances. It boasts compact size, excellent performance, and a communication band of 902-928MHz. It supports a transmission distance of 40km and above and a transmission rate of 250kbps.

Features:
1. No distinction between transmitter and receiver. Each module integrates a USB serial port chip, and USB and UART interfaces can be automatically switched (USB of priority);
2. Operating frequency range 902-928MHz, ISM band;
3. Transmit circuit adopts a low-noise amplifier greater than 20DB, and a low-pass filter unit is added;
4. Transmit power can be adjusted and the maximum transmission power is 1W;
5. Receiving circuit front highly sensitive LNA and SAW circuit;
6. Outdoor communication distance can reach 40km or more in a straight line (depending on antenna performance and communication rate requirements);
7. Air data rate up to 250Kbps;
8. Dual antenna interface support antenna diversity and differentiated antenna configuration;
9. Support local radio AT command configuration and remote radio RT command configuration;
10. With module temperature monitoring, automatic duty cycle adjustment according to temperature to avoid over-temperature;
11. Operating temperature -40 to + 85℃.
