P8 Radio Telemetry
Product Introduction
P8 Module is an ultra-long data transmission module of unmanned system. It adopts the communication frequency band of 840MHz. It has a transmission distance of 60km and a transmission rate of 345Kbps. It supports opoint-to-multiple, and relay communication, meet communication requirements in multiple application scenarios.
The wide voltage input of the 3S-12S battery supported by P8 covers the working voltage of most of the current UAVs. No additional BEC is required for voltage conversion.
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.
The aviation aluminum alloy shell has good thermal conductivity, light weight, high strength and corrosion resistance, and has good electromagnetic shielding efficiency. The design of heat dissipation grooves on the shell surface increases the heat dissipation efficiency.
