3DR Radio Telemetry Kit 433MHz 500mW

The 3DR 433MHz Telemetry Kit (500mW version) is a long-range, high-power wireless communication system designed for unmanned aerial vehicles (UAVs), drones, RC planes, and other robotic telemetry systems. It offers a full-duplex data link between a ground station and an autopilot (such as Pixhawk, APM, or similar). Operating in the 433MHz ISM band, this telemetry kit is capable of achieving reliable data communication over several kilometers, depending on antenna setup and environmental conditions.

Features:
- Long-range transmission: up to 2–5 km with line-of-sight and suitable antennas
- High power output: 500mW (27dBm) for robust signal in noisy environments
- Full-duplex communication with auto retransmission and error correction
- Plug-and-play with most flight controllers (APM, Pixhawk, etc.)
- Built-in SiK firmware with adaptive flow control, frequency hopping, and error detection
- Configurable via Mission Planner/QGroundControl
- Includes both air module and ground module
- Uses FTDI-compatible USB interface for easy computer connection
- LED indicators for connection status and data activity
