Generic 3DR Radio Telemetry 500mW Kit - 915MHz
This 915MHz 500mW telemetry kit provides a full-duplex MAVLink serial link for connecting flight controllers to ground station software like Mission Planner, enabling real-time telemetry, mission planning, and live flight data monitoring for UAVs.
Features
- 500mW adjustable output power on the 915MHz ISM band for extended telemetry range.
- Full-duplex communication using adaptive Time-Division Multiplexing (TDM) for reliable bidirectional data flow.
- Based on the HM-TRP module with Si1000 microcontroller and Si4432 RF IC, running open-source SIK firmware.
- Features both Micro-USB and UART interfaces, allowing connection to computers via OTG or direct serial links to flight controllers.
- Configurable via AT commands and fully compatible with MAVLink-based ground control stations like Mission Planner and APM Planner.

This telemetry kit utilizes two interchangeable transceiver modules, eliminating the traditional air/ground designation. Each module can function as either end of the link, providing flexibility in system setup. The core HM-TRP modules employ a Si1000 8051 microcontroller paired with a Si4432 wireless transceiver, delivering robust 500mW output power on the 915MHz frequency band with Frequency-Hopping Spread Spectrum (FHSS) and Listen-Before-Talk (LBT) protocols for interference resilience.
The system establishes a transparent serial tunnel, framing MAVLink protocol data for transmission. It supports advanced features like configurable duty cycles and built-in forward error correction, capable of correcting up to 25% data bit errors. This makes it suitable for demanding FPV and autonomous drone applications where reliable telemetry for GPS position, battery voltage, artificial horizon, and waypoint navigation is critical.
