Product overview
The ComNav U702 Datalink Module provides half-duplex RX/TX communication using the LoRa protocol and CSS modulation. Designed for integration into GNSS systems, including lawn mowers, it combines a compact surface-mounted construction with frequency-hopping support and robust electromagnetic compatibility. Its working range extends from 0.8km to 1.5km. Built-in LoRa technology supports interference protection, high reception sensitivity and low-error data transmission in harsh environments.
The module measures 17×22×3mm with its connector and weighs 5 g. It operates from a +3.3V ~ +3.6V DC supply, with emission current below 0.2A. Connection features comprise an LGA 2×16-pin I/O interface with 1.27mm pin pitch, two LVCMOS 3.3V DTE-DCE interfaces and an IPEX female antenna connector. Frequency options are 410–470MHz, 863–870MHz and 902–928MHz, with five air baud rates spanning 500bps to 18000bps.
