Holybro P900 Radio Module 900MHz 1W Based on Microhard Chip Long Range for Pixhawk / APM / PaparazziUAV RC FPV Racing Drone     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.     FCC ID :NS913P900     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.          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      SPECIFICATIONS            Power Consumption     Supply voltage: DC7~35V from 4-position JST-GH Transmit current: 200 mA/7V at 20dBm 350mA/7V at 27dBm 800 mA/7V at 30dBm Receive current: 100 mA Weight: 42g (without antenna)     PIN MAP          Dimensions          Package Includes:     Microhard P900 Radio (1pc)     1x  Microhard P900 Radio 1x  Antenna 1x  XT30 Power cable 1x  GH 6P to 6P cable  1x  Metal Pin     Microhard P900 Radio (1pair)     2x  Microhard P900 Radio 2x  Antenna 2x  XT30 Power cable 1x  GH 6P to 6P cable  1x  Metal Pin     Download     Microhard_P900_Radio_QuickStartGuide PicoConfig 1.
