Rich Port Interface And Easy to Use5 I/O port is provided, allowing the possibility to achieve 5 digital inputs and outputs. It’s compatible with 3 pulse output, 3 analog input and 2 pulse counting function. Also, it provides standard RS232 and RS485 interface ports; can be directly connected to serial devices.Industry Leading Max Transmission Distance of 8 KMThe Four-Faith LoRa module adopts a LoRa modulation technique, acquired through many years of wireless network experiences to achieve a maximum transmission distance of 8 km. Perfectly solving the problematic environment of small amounts of data transmission over long distances, providing an ideal solution to all industries wireless networking needs.Excellent Anti-Interference FeaturesUsing the forward error correction technology to increase redundant information during transmission, any errors are corrected immediately upon arriving at the receiving end. Combine this with the Four-Faith channel conflict detection optimization technique to solve the problem of node data and packet loss to greatly improve the link robustness.Module Supports Over-the-Air UpdatesThe Four-Faith LoRa modules support over-the-air updates along with remote maintenance, so technical personnel need not be on site to perform these tasks, significantly reducing labour costs and improving management efficiency.-148dBm Ultra-High Receiver SensitivityModulation techniques created a unique spectrum widening process, allowing the receiver sensitivity to reach -148dBm. This makes it suitable for use in environments where stable long-distance data transmission is a top priority.
