Introduction

The LAMBDA68 RF module is a class leading, cost effective radio module featuring the Semtech LLCC68 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 provides a simple digital interface and direct antenna connection. This enables a plug in RF solution with maximum efficiency. Programming of the module is via SPl interface. The LAMBDA68 Module is CE compliant. Providing that certain procedures are followed.
