Holybro Microhard Telemetry Radio P840
The Holybro Microhard Telemetry Radio P840 is a robust, long-range RF module designed for high-reliability telemetry and command links between ground stations and UAVs. It operates in the 840 MHz ISM band, supports 7-35V input, and integrates seamlessly with flight controller telemetry ports for use with ArduPilot, PX4, and other autopilot systems.
Features
- Operates in the 840 MHz ISM band for long-range, license-exempt telemetry.
- Wide 7-35V DC input range with integrated high-voltage BEC for direct vehicle power.
- Supports transparent serial link rates up to 230 kbps with a claimed range up to 100 km.
- Features Frequency Hopping Spread Spectrum (FHSS) for robust interference resistance.
- Integrated USB Type-C port and diagnostic interface for easy configuration via AT commands.

The Holybro Microhard P840 Telemetry Radio integrates a Microhard Pico Series RF module, engineered for mission-critical wireless serial communication in UAV and robotic applications. It employs Frequency Hopping Spread Spectrum (FHSS) technology within the 840-840.5 MHz band to provide a secure, low-latency data link resilient to interference, making it suitable for Point-to-Point and Point-to-Multipoint network topologies.
Its design includes a high-efficiency voltage regulator accepting 7-35V input, allowing direct connection to vehicle power systems without an external BEC. The module provides a transparent serial bridge between flight controller telemetry ports and ground control stations, with error detection via 32-bit CRC and configurable ARQ retransmission to ensure data integrity over extended distances.
