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.
