INTRODUCTION
The LL-RLP-20 is a highly-integrated, low power, bi-directional radio transceiver module
optimized for use in the 915 MHz ISM and the 868 MHz ETSI frequency bands. The module
uses a Frequency Modulated Chirp (Semtech's LoRa
TM
modulation) to maximize range while
minimizing power consumption and interference.
