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.
BENEFITS
–USB Type-C port, integrated USB to UART converter
–6-position JST-GH connector, can be directly connected to the TELEM port on various flight controller such as the pixhawk 4
–High voltage BEC onboard, Support DC7~35V voltage supply
–UART transmission LED indicator
–Three-stage RSSI LED indicator  
–Transmission within a public, license-exempt band of the radio spectrum
–Transparent, low latency link rates up to 276 kbps
–Supports a robust true Mesh operation with auto-routing
–32 bits of CRC, selectable retransmission and forward error correction
–Separate diagnostics port, transparent remote diagnostics and online network control

Config Button
Holding this button while powering-up the radio will boot the unit into COMMAND mode: the default serial interface will be active and temporarily set to operate at its default serial settings of 9600/8/N/1.



USB
USB TypeC Port. Internal USB to Serial Converter. The USB port of Holybro P900 Radio is different from MicroHard P900 Enclosed. The USB port of P900 Enclosed provides access to the Diagnostic Port. But Holybro P900 Radio¡¯s USB port Provides access to the Serial data Port. That means you can connect Holybro P900 Radio to your ground station via USB port directly. USB Vbus only power the USB to Serial chip, and don¡¯t power the Radio.



Data Port
6-position JST-GH. Data Port is used to connect to the telemetry port of a flight controller. When USB TypeC port don¡¯t connect, this connector connects to the Serial data Port automatically. When USB TypeC is pluged in, this connector is floating. Data Port don¡¯t power the Radio.



Diagnostic Port
4-position JST SH. This connector connects to the Diagnostic Port. If you use PicoConfig application or special diagnostic commands to config the Radio, you should connect to this port. Diagnostic Port is 3.3V logic level compatibility. A USB to Serial board is needed for connecting the radio to your computer.

Power Port
4-position JST-GH. The input Voltage range is 7-35 Vdc. The Radio is powered by the Power Port only.
Please connect the power supply when in use and configuration.



Default Setting
The default setting of microhard P900 module do not match the telemetry setting of flight controller.
Holybro P900 Radio have been configured to Point to Point Operating Mode and 57600 Serial Baud Rate in
factory. Using these parameters, the Radio communicates successfully with the pixhawk series flight
controller. After Firmware Update or resetting the Radio, you need to re-config them as following.

In Point to Point operating modes, there must be a master to provide network synchronization for the
system, so one Radio should be configured to PP Master and another should be configured to PP Remote.
Refer to for the detail information of Radio Configuration.
