Description

The Holybro SiK Telemetry Radio V3 provides a reliable, transparent serial link for telemetry data, utilizing open-source firmware specifically engineered for low-latency MAVLink communication. Its adaptive TDM UART interface ensures efficient two-way data flow between the autopilot and ground station software.

Built for durability in UAV applications, the module supports configurable power output and duty cycles via Mission Planner or APM Planner, allowing pilots to optimize range and compliance with local 433 MHz regulations. The compact design and included adapter cables facilitate seamless integration into a wide array of multirotor and fixed-wing platforms.

Key Features

  • High-power 500mW RF output (adjustable) with -117 dBm receive sensitivity for robust telemetry links.
  • Open-source SiK firmware with MAVLink optimization and Frequency Hopping Spread Spectrum (FHSS) for interference resistance.
  • Full-duplex adaptive TDM UART interface ensures reliable, simultaneous two-way communication.
  • Comprehensive connectivity suite includes Micro-USB port, JST-GH-6P, and Molex DF13 connectors for broad FC compatibility.
  • Interchangeable air/ground unit design allows flexible module deployment across vehicle and base station roles.
  • RP-SMA antenna connector supports standard 433 MHz antennas for range extension.
  • Configurable via standard ground control station software including Mission Planner and QGroundControl.

Applications

  • Establishing long-range MAVLink telemetry for ArduPilot or PX4-based fixed-wing UAVs.
  • Providing real-time telemetry and mission data downlink for Pixhawk-standard multirotor drones.
  • Configuring as a ground station radio for Mission Planner or QGroundControl control and monitoring.
  • Enabling bidirectional telemetry for automated mission planning and vehicle status monitoring.
  • Integrating into custom UAV platforms requiring a reliable, configurable 433 MHz serial link.

Frequently Asked Questions

What flight controllers is the Holybro SiK Radio V3 compatible with?

The SiK Radio V3 is plug-and-play compatible with Pixhawk Standard flight controllers, Pix32, and Pixhawk 2.4.6 via the included JST-GH to JST-GH and JST-GH to Molex DF13 adapter cables. It establishes a transparent serial link for MAVLink telemetry with ArduPilot and PX4 autopilots.

Can I adjust the output power of the 500mW SiK Radio?

Yes, the 500mW maximum RF output power is adjustable via ground control station software like Mission Planner or QGroundControl. This allows you to reduce power for compliance with local 433 MHz regulations or to optimize battery consumption during flight.

What is the purpose of having two identical radio modules in the kit?

The kit includes two interchangeable modules so one can be configured as the air unit (connected to the flight controller) and the other as the ground unit (connected to your computer or ground station). The open-source SiK firmware allows either module to fulfill either role.

What type of antenna connector does the module use, and what range can I expect?

The module uses an RP-SMA female connector for attaching standard 433 MHz antennas. With the included antennas, typical line-of-sight range exceeds 300 meters. Using high-gain directional antennas (like a patch antenna) on the ground station can extend this range to several kilometers.
