Description

The Holybro Sik Telemetry Radio V3 provides a robust, open-source wireless telemetry solution for UAVs. Its design focuses on reliable, long-range communication using the SiK firmware stack, which includes error correction capable of recovering up to 25% of bit errors. The module supports Frequency Hopping Spread Spectrum (FHSS) to mitigate interference and offers a configurable duty cycle to adapt to local regulatory requirements.

Engineered for seamless integration, the radio interfaces via a 3.3V UART and a 6-position JST-GH connector, making it directly compatible with a wide range of flight controllers running ArduPilot or PX4. The interchangeable air and ground unit design simplifies setup, allowing either module to function as transmitter or receiver based on configuration within your ground control software.

Key Features

  • Open-source SiK firmware ensures transparency, community support, and customization for MAVLink protocols.
  • Robust RF link with Frequency Hopping Spread Spectrum (FHSS) enhances resistance to signal interference and noise.
  • Advanced error correction algorithms can recover up to 25% of bit errors, maintaining data integrity over longer distances.
  • Configurable output power and duty cycle via Mission Planner or APM Planner for compliance with local radio regulations.
  • Low-power design with 100 mA transmit current and 25 mA receive current optimizes system power consumption.
  • Dual interface options include a dedicated 6-pin JST-GH connector for flight controller integration and a Micro-USB port (with Type-C adapter) for direct PC connection.
  • FT230X/FT231 USB-to-UART IC provides reliable serial communication for configuration and ground station linking.

Applications

  • Establishing telemetry links for Pixhawk-based autonomous drones and rovers.
  • Long-range MAVLink communication for fixed-wing UAVs and VTOL aircraft.
  • Real-time telemetry and mission planning for ArduPilot and PX4 Pro powered vehicles.
  • Ground station connectivity for data logging, parameter tuning, and live flight monitoring.
  • Building redundant telemetry systems for professional mapping and inspection drones.

Frequently Asked Questions

What is the maximum range of the Holybro Sik Telemetry Radio V3?

Out of the box with stock antennas, the radio typically achieves ranges better than 300 meters. With the use of higher-gain directional antennas, such as a patch antenna on the ground station, the range can be extended to several kilometers, depending on environmental conditions and regulatory power limits.

How do I configure the radio's power and frequency settings?

The Holybro Sik Radio V3 is configured through standard ground control station software like Mission Planner, APM Planner, or QGroundControl. You can connect the ground unit via its Micro-USB port (with the included Type-C adapter) to your PC and use the software's telemetry radio configuration tools to set parameters like output power, duty cycle, and frequency hopping channels.

Is this radio compatible with my flight controller running Betaflight?

No, the Holybro Sik Telemetry Radio is specifically designed for MAVLink-based autopilot systems like ArduPilot and PX4 Pro, which are common on Pixhawk-standard flight controllers. It is not intended for direct use with Betaflight, which typically uses other protocols like CRSF or SmartAudio for telemetry and control.

What is the difference between the 433 MHz and 915 MHz versions?

The 433 MHz version is intended for use in regions like Europe, Africa, and parts of Asia, while the 915 MHz version is for North America, Australia, and other regions. You must select the frequency that is legally permitted for unlicensed telemetry use in your country to avoid interference and comply with local radio regulations.
