Microhard P900 Radio
Holybro P900 Radio integrates microhard Pico Series P900 RF module which is capable of delivering high-performance wireless serial communications in robust and secure Mesh, Point to Point or Point to Multipoint topologies.
P900 Radio operate within the 902-928 MHz ISM frequency band, using frequency hopping spread spectrum (FHSS) technology, providing reliable wireless asynchronous data transfer between most equipment types which employ a serial interface.
P900 Radio may be configured as a Primary Coordinator, Secondary Coordinator, Standby Coordinator or Remote in a Mesh Topology, or a Master, Repeater or Remote in a PP or PMP Topology. This versatility is very convenient for the user.
P900 Radio is configured using AT commands through the Data port or using PicoConfig application through the Diagnostic Port.
