1.0 INTRODUCTION
The DLP-RFS1231 is a low-cost module for transmitting and receiving digital data via radio frequency.
All of the DLP-RFS1231’s electronics (including an antenna) reside on a single PCB, and all
operational power is derived from a single supply voltage.
The transceiver design consists of a Semtech SX1280 low-power, integrated UHF transceiver and an
antenna switch for selecting between the on-board chip antenna and an optional external antenna.
The hardware is designed for maximum range and optimum battery life.
