DRF1272F module consists of RFIC SX1272, 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. DRF1272F operates at 1.8~3.6V with extra low standby current which makes it suitable for battery powered-up applications. Because DRF1272F is purely hardware module and it adopts ±10ppm crystal which the resolution of it places a important role in calculating spreading factor, bandwidth, etc. Users need to read the datasheet of SX1272 carefully in order to use the module in the best performance.
