RF LoRa
TM
DS-RFLoRa-7
Description
The RF-LoRa module is an extremely high performance, cost effective radio module featuring the
Semtech SX1272 LoRa™ long range providing ultra-long range, spread spectrum communication and
high interference immunity within minimal current consumption.
This module including crystal, RF Changeover switch, impedance matching network and track layout
provide a simple digital interface and direct antenna connection. This enables a plug in RF solution with
maximum efficiency. Programming of the module is via SPI interface.
Using the RF-LoRa enables a fast and easy to market solution with cost effective license exempt
hardware.
The RF-LoRa Module is CE compliant. Providing that certain procedures are followed. (please refer to
application schematic later in this datasheet).
