2AP22-HT08Microhard Radio P900

P a g e | 1 www.holybro.com Model:HT08 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 Microhard Radio P900 Port.

P a g e | 3 www.holybro.com Status LEDs P900 Radio have 6 status LEDs, there are three blue, two orange and one green LEDs. The meaning of the different LEDs are: Power LED(green) This LED will illuminate when the P900 Radio is connected to a power source (7-35VDC). TX LED (orange) When illuminated, this LED indicates that the Radio is transmitting data over the air. RX LED (orange) This LED indicates that the Radio is synchronized and has received valid packets. RSSI LEDs (3x Blue) As the received signal strength increases, starting with the furthest left, the number of active RSSI LEDs increases. Signal strength is calculated based on the last four valid received packets with correct CRC. The value of RSSI is reported in S123. P a g e | 4 www.holybro.com RSSI LEDs(blue) - indicate the receive signal strength. RSSI <20% LED-20 off LED-50 off LED-100 off 20%<RSSI<50% LED-20 on LED-50 off LED-100 off 50%<RSSI<80% LED-20 on LED-50 on LED-100 off 80%<RSSI LED-20 on LED-50 on LED-100 on 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. P a g e | 5 www.holybro.com 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 <Pico Series P900.Operating Manual.v1.8.7> for the detail information of Radio Configuration.
