This module is a type of low-cost RF front-end transceiver module based on SX1278 from Semtech Corporation. It retains the advantages of RFIC SX1278 while simplifying the circuit design. The high sensitivity (-136dBm) in LoRa modulation and 20dBm high power output make the module suitable for low range and low data rate applications.
The module consists of RFIC SX1278, thin SMD crystal, and antenna matching circuit. The antenna port is well matched to the standard 50 Ohm impedance. Users don't need to spend time on RF circuit design and choose suitable antennas for different applications. The module operates at 1.8~3.6V with extra low standby current, making it suitable for battery-powered applications. It is a purely hardware module and adopts a ±10ppm crystal, where the resolution plays an important role in calculating spreading factor, bandwidth, etc.
