LoRa SX1278 433MHZ Long Range RF Wireless Module with Wireless alarm system

Lora SX1278 433MHZ Long Range RF Wireless Module with Wireless alarm system. This module is a type of low-cost RF front-end transceiver module based on SX1278 from Semtech Corporation. It keeps the advantages of RFIC SX1278 but simplifies 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 an antenna matching circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don’t need to spend time in RF circuit design and choose suitable antennas for different applications. The module operates at 1.8~3.6V with extra-low standby current which makes it suitable for battery powered-up applications. Because it is purely a hardware module and it adopts a 10ppm crystal which the resolution of it places an important role in calculating spreading factor, bandwidth, etc.
