Ai-Thinker Ra-01S LoRaWAN Module
The Ai-Thinker Ra-01S LoRa Module is a high-performance wireless communication solution tailored for long-range, low-power applications in the Internet of Things (IoT). Built around the Semtech SX1268 chip, this module operates in the 410-525MHz frequency band, aligning with regional regulations for sub-GHz communication. The Ra-01S leverages LoRa modulation technology, a spread spectrum technique derived from chirp spread spectrum (CSS), to deliver exceptional range, reliability, and power efficiency, making it an excellent choice for battery-powered devices in smart cities, industrial automation, and agricultural monitoring.
Features:
- LoRa™ modem.
