Ai Thinker LoRa-Ra-01 RF Transceiver Module

The Ai-Thinker LoRa Ra-01 RF Transceiver Module is a long-range, low-power wireless communication module based on the Semtech SX1278 LoRa chip. Designed for IoT, smart metering, remote monitoring, and industrial control applications, the Ra-01 provides reliable communication over several kilometers with excellent interference immunity. Operating in the 433MHz ISM band, this module supports LoRa spread spectrum modulation, offering high sensitivity and strong anti-interference capability. It is ideal for low-data-rate applications where long-distance transmission and ultra-low power consumption are essential.
