Holybro Microhard Telemetry Radio integrates microhard Pico Series RF module which is capable of delivering high-performance wireless serial communications in robust topologies, such as Point to Point, Point to Multipoint and secure Mesh (Mesh only available on P900).

It uses frequency hopping spread spectrum (FHSS) technology, providing reliable wireless asynchronous data transfer between most equipment types which employ a serial interface. Fixed frequency is available on the P840 version. The radio is configured using AT commands through the Data port or using PicoConfig application through the Diagnostic Port.

P900 Radio operate within the 902-928 MHz ISM frequency band while the P840 operate within 840-845Mhz, and P400 operate within 410-480MHz. You can select your radio based on your country’s available frequency band.
