Description
Ra-01 LoRa SX1278 433MHz Wireless Module (10KM Range)
The Ra-01 is a high-performance long-range wireless transceiver module developed by
Ai-Thinker, based on the Semtech SX1278 chip. Using LoRa™ spread
spectrum technology, it overcomes the limitations of traditional RF communication, offering
extraordinary interference immunity and ultra-long-distance data transmission (up to 10KM).
It is the ultimate solution for IoT projects, remote sensing, and smart agriculture.
Key Features
- Extreme Long Range: Capable of transmitting data up to 10KM in open-field (Line of Sight) conditions.
- LoRa™ Modulation: Provides superior anti-interference performance compared to standard FSK/GFSK.
- Ultra-Low Power Consumption: Features a sleep mode current of less than 1µA, perfect for battery-powered sensors.
- High Sensitivity: Industry-leading sensitivity down to -148 dBm.
- Compact Form Factor: Small SMD package (17 x 16 mm) with an integrated spring antenna for easy integration.
