Description

The Holybro Microhard Telemetry Radio integrates the industrial-grade Microhard Pico Series RF module, delivering high-performance, low-latency wireless serial communications for demanding UAV applications. It employs Frequency Hopping Spread Spectrum (FHSS) technology to ensure reliable data transfer in noisy RF environments, supporting transparent link rates up to 276 kbps. The system is designed for robust topologies including Point-to-Point, Point-to-Multipoint, and true Mesh networking with auto-routing capabilities.

Engineered for integration with professional flight control systems, the radio features a high-voltage BEC supporting 7-35V DC input, making it compatible with 2S to 6S LiPo setups without an external regulator. The unit includes clear LED indicators for UART transmission and three-stage RSSI strength, alongside comprehensive error detection with 32-bit CRC and selectable ARQ (Automatic Repeat reQuest) for data integrity. Its separate diagnostics port enables transparent remote configuration and real-time network health monitoring.

Key Features

  • Microhard Pico Series RF Core: Delivers industrial-grade, reliable wireless serial communication with FHSS technology for interference resistance.
  • Wide Input Voltage Range: Integrated high-voltage BEC supports 7-35V DC, compatible with 2S to 6S LiPo batteries and vehicle power systems.
  • Direct Autopilot Interface: 6-pin JST-GH connector provides a direct, solder-free connection to the TELEM port on Pixhawk, Cube, and other flight controllers.
  • Advanced Network Topologies: Supports robust Point-to-Point, Point-to-Multipoint, and true Mesh networking with automatic routing for complex mission profiles.
  • Comprehensive Diagnostics & Configuration: Features a separate diagnostic port and USB Type-C with integrated UART converter for setup via AT commands or the PicoConfig GUI application.
  • Visual Status Indicators: Includes UART transmission LED and a three-stage RSSI LED indicator for immediate link quality assessment.
  • High Data Integrity: Utilizes 32-bit CRC error detection, selectable packet retransmission (ARQ), and forward error correction for reliable data transfer.

Applications

  • Long-Range Fixed-Wing UAVs: Providing telemetry and command links for mapping, surveillance, and agricultural drones operating beyond visual line of sight (BVLOS).
  • Industrial & Inspection Drones: Enabling reliable data transmission for infrastructure inspection, power line monitoring, and search-and-rescue operations where RF penetration is crucial.
  • Mesh Networked Swarms: Deploying multiple units in a mesh topology for coordinated flight missions, data relay, and redundant communication paths in complex environments.
  • High-Altitude & Long-Endurance Platforms: Integrating with HALE UAVs and autonomous vehicles requiring robust, license-exempt telemetry over extended distances.
  • Ground Control Station Links: Establishing a primary or redundant wireless link between a mobile ground station and the airborne vehicle for mission control and real-time data streaming.

Frequently Asked Questions

What is the operating frequency band of the Holybro Microhard P900 Radio?

The Holybro Microhard P900 Radio operates in the 902-928 MHz ISM (Industrial, Scientific, and Medical) band. This license-exempt frequency band is known for good penetration through obstacles like foliage and buildings, making it suitable for long-range and non-line-of-sight UAV applications. Always verify local regulations regarding the use of this frequency band in your country.

How do I connect the Microhard Radio to my flight controller?

The radio connects directly to your flight controller's TELEM port using the included 6-pin JST-GH to 6-pin JST-GH cable. Simply plug the cable into the radio's 6-pin Data port and the other end into the TELEM port on a Pixhawk, Cube, or other compatible autopilot. Power is supplied separately via the 4-pin JST-GH connector using the included XT30 cable connected to your vehicle's main battery or power distribution board.

What is the difference between the P900 and P840 models?

The primary difference is the operating frequency band. The P900 model operates in the 902-928 MHz range, while the P840 operates in the 840-845 MHz range. The P900 also supports true Mesh networking topology, whereas the P840 does not. The P840 may offer a fixed-frequency mode in some regions. Selection should be based on the legally available frequency band and specific networking requirements in your country.

What input voltage does the radio support, and how is it powered?

The radio features an integrated high-voltage BEC that supports a wide input range of 7 to 35 volts DC. This allows it to be powered directly from common 2S to 6S LiPo battery packs without an external voltage regulator. Power is supplied via the 4-pin JST-GH connector using the included XT30 cable, which should be connected to your drone's main battery leads or PDB.

How do I configure the Microhard Radio settings?

Configuration is performed via AT commands sent through the Data port or, more conveniently, using the Microhard PicoConfig Windows application via the USB Type-C Diagnostic Port. The USB port has an integrated USB-to-UART converter, allowing you to connect the radio directly to a computer to change network IDs, RF power, data rates, and mesh parameters without needing a separate FTDI adapter.
