Four-Faith F8L10D-N – LoRa Module

The F8L10D LoRa module is a kind of embedded device that provides data transfer function by LoRa network. It provides ultra-long range spread spectrum communication. The product uses high-performance industrial-grade LoRa solution, supporting a transparent data transmission function. Further characteristics include a low power consumption design, the lowest working current is less than 2uA; supply for multiple I/O channels, compatible analog inputs and pulse input counters. It has been widely used in M2M fields, such as electric power, intelligent traffic, wireless metering, industrial automation, telemetry, water supply, environment protection, weather, and so on.
