P8 Telemetry

840.5MHz ~ 845MHz frequency band.
40km transmission distance.
345Kbps air rate.
Supports one-to-one and relay modes.
Built-in BEC; supports 3S ~ 12S power input.
Dual-end switching reduces operational costs.

840-845 MHz Communication Band

840-845MHz is adopted to avoid interference from otherdevices in 433MHz, 915MHz and 2.4g communication frequency bands.

850.5MHz ~ 845MHz

345 kbps Air Speed, 40 km Range

Using Adaptive bandwidth, automatic interference-avoidance frequency hopping, and bidirectional telemetry technologies, the transmission distance reaches 40km and the transmission ratereaches 345kbps.

Dual-End Switchover

P8 has built-in TTL and USB ports, and the air terminal and ground terminal can be switched at will. If there is damage, it can be paired with other modules to reduce the use cost.
