1. Product Introduction

- Key Features

Ra-01

  • The Ra-01 LoRa module utilizes the SX1278 RF chip featuring SEMTECH's LoRa™ modulation.
  • This technology enables ultra-long-range spread spectrum communication with high sensitivity (-148dBm), +20dBm transmit power, enhanced interference immunity, and minimized current consumption.
  • Compared to traditional modulation, LoRa™ significantly improves blocking resistance and selectivity, resolving the inherent trade-off between range, interference immunity, and power consumption. Typical applications include automated meter reading, building/home automation, security systems, and remote irrigation.
