CUAV P8 Radio Telemetry 840-845MHz

The CUAV P8 is a long-range 840–845 MHz telemetry radio for ArduPilot and PX4 aircraft, suited to survey, mapping and long fixed-wing or VTOL missions. Choose the Sky Unit for the aircraft, the Base Unit for the ground station, or the Sky + Base Set for a complete link.

Key features

• Range: up to 60 km in clear line of sight; CUAV gives about 40 km as a typical reference distance, depending on antennas and terrain.
• 345 kbps air rate: serial baud from 300 bps to 230 kbps, 57600 by default.
• Adjustable power: 100–1000 mW (20–30 dBm), 1000 mW by default; receive sensitivity down to -109 dBm.
• Robust link: frequency hopping or fixed frequency, 32-bit CRC with ARQ, plus Hamming, BCH, Golay, Reed-Solomon and Viterbi error correction.
• Flexible networks: point-to-point, point-to-multipoint and relay modes.
• Direct battery power: runs on 12–60 V (3S–12S) with no extra BEC; every unit has a JST-GH 6-pin serial port and USB-C, so either end can work as the air or ground radio.

The Sky Unit comes with an 840 MHz antenna, CUAV V5/X7-series and Pixhack data cables and an XT30 power lead; the Base Unit comes with an 840 MHz antenna, an XT30-to-XT60 power lead and a USB-C cable; the Sky + Base Set includes both kits. Power each radio from its own supply rated above 2.5 A, never from the flight controller.
