Description

The SIYI HM30 system employs robust digital transmission technology to provide a stable, high-definition video link critical for FPV flight and aerial observation. Its air unit is engineered for minimal size and weight, featuring active cooling and a broad 11-16.8V input range that supports direct connection to 3S-4S LiPo batteries and can be expanded for high-voltage industrial platforms.

The ground unit serves as a compact command center, combining video reception, telemetry data display, and RC signal relay. Its IP53-rated enclosure and support for quick-release NP-F series batteries ensure reliability in field operations. The system’s low-latency performance and integrated datalink make it suitable for demanding applications beyond recreational FPV, including mapping, inspection, and autonomous drone missions.

Key Features

  • Long-Range HD Video: Digital transmission provides clear 1080p/720p video with a theoretical maximum range of 30 kilometers under optimal, unobstructed conditions.
  • Integrated Telemetry Datalink: Built-in UART interface supports bidirectional MAVLink telemetry for integration with PX4 and ArduPilot flight controllers.
  • Multi-Protocol Control Relay: Air unit outputs 16 channels of S.Bus and 5 channels of PWM, allowing direct control of gimbals, servos, or flight modes.
  • Portable & Field-Ready Ground Station: Compact design with OLED status display, multiple antenna options (5 dBi omni & 11 dBi long-range), and IP53 weather resistance.
  • Flexible Power Architecture: Air unit accepts 11-16.8V (3S-4S) natively, with external BEC support for up to 18S (75.6V) systems for heavy-lift drones.
  • Comprehensive Connectivity: Includes Ethernet port for network integration, USB-C for video output/firmware updates, and dedicated ports for RC input and power distribution.

Applications

  • Long-range FPV exploration and mapping drones requiring stable HD video and telemetry links.
  • Aerial cinematography platforms where low-latency, high-quality live feed is crucial for camera operators.
  • Industrial inspection and surveillance UAVs integrated with PX4 or ArduPilot for automated missions.
  • Heavy-lift and agricultural drones needing reliable control relay (S.Bus/PWM) and video transmission over several kilometers.
  • Research and development platforms requiring bidirectional MAVLink telemetry and Ethernet connectivity for ground station networks.

Frequently Asked Questions

What is the real-world video range of the SIYI HM30 system?

The specified 30km range is a theoretical maximum achieved under ideal, unobstructed conditions with clear line-of-sight and no RF interference. Practical operational range will be less, depending on antenna selection, output power settings, local regulations, and environmental factors like terrain and weather.

Can I use the HM30 Air Unit with a 6S or higher voltage battery?

Yes, but not directly. The air unit's native input range is 11-16.8V (3S-4S). For use with 6S (22.2V) or higher voltages up to 18S, you must use an external step-down BEC (voltage regulator) that provides a stable output within the air unit's specified input range to avoid damage.

How do I integrate the HM30 system with my ArduPilot or PX4 flight controller?

Use the included telemetry cable to connect the UART datalink port on the HM30 ground unit to a telemetry port on your flight controller. Configure the corresponding serial port in your flight controller firmware (e.g., Mission Planner, QGroundControl) for MAVLink telemetry to enable bidirectional data transmission like GPS position, battery voltage, and flight mode.

What video outputs are available from the HM30 Ground Unit?

The primary video output is via the USB Type-C port, which can stream video to a compatible display or capture device. The unit also has an Ethernet port, which can be used for network streaming or integration when configured via the provided RJ45 cable.

Does the included FPV camera support manual camera control settings?

The provided specifications indicate the camera offers configurable video parameters. Settings such as resolution (1080p/720p), bitrate, and potentially other image parameters are typically adjustable via the system's OSD menu or a dedicated configuration software provided by SIYI, allowing optimization for different lighting conditions and bandwidth requirements.
