This is Ai Thinker LoRa-Ra-01 RF Transceiver Module.

This LoRa 433MHz module designed by AI-THINKER, which based on the chip SX1278. The SX1278 RF module is mainly used for long-range spread spectrum communication. It can resist Minimize current consumption. Thanks to SEMTECH’s patented LoRa™ modulation technology, the SX1278 has a high sensitivity of -148 dBm with a power output of +20 dBm, a long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, LoRa™ Modulation technology in anti-blocking and selection also has obvious advantages, to solve the traditional design can not take into account the distance, interference and power consumption.

  1. Automated Meter Reading.
  2. Home and Building Automation.
  3. Wireless Alarm and Security Systems.
  4. Industrial Monitoring and Control.
  5. Long-range Irrigation Systems.
