The Ai-Thinker LoRa Series Module (Ra-01H) is designed and developed by Ai-Thinker. This module is intended for long-distance spread spectrum communication. It uses the SX1276 RF chip (see Figure 1), which is widely used in LoRa remote modems for ultra-long-distance communication.
The SX1276 supports strong anti-interference capabilities and minimizes current consumption. With the help of SEMTECH's patented LoRa technology, the SX1276 achieves a high sensitivity of -148 dBm and an output power of up to +20 dBm, enabling long-range transmission and high reliability.
Compared to traditional modulation techniques, LoRa modulation has clear advantages in terms of anti-blocking and signal selection. It addresses the typical challenges of balancing distance, anti-interference, and power consumption in wireless system design.
Applications include: automatic meter reading, home/building automation, security systems, and remote sensing.
