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.
