XL1278 LORA MODULE 

XL1278-SMT 433MHz LORA Trans-receiver MODULE 

XL1278F 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 (-139dBm) in LoRa modulation and 20dBm high power output make the module suitable for low range and low data rate applications.

XL1278F module consists of RFIC SX1278, thin SMD crystal and 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. XL1278F operates at 1.8~3.6 Volts with extra low standby current which makes it suitable for battery powered-up applications. Because XL1278F is purely hardware module and it adopts ±10ppm crystal which the resolution of it places a important role in calculating spreading factor, bandwidth, etc.
