[Introduction]：E22-170M22S is an independently developed, ultra-compact, 170.125MHz surface-mount LoRa wireless module based on Semtech's new-generation LoRa™ RF chip, the SX1262. By utilizing the imported SX1262 as its core, the module offers improved anti-interference performance and communication range compared to previous-generation LoRa™ transceivers. Utilizing the latest LoRa™ modulation technology, its anti-interference performance and communication range far exceed those of existing FSK and GFSK modulation methods. The LoRa module is mainly targeted at smart homes, wireless meter reading, scientific research and medical treatment, as well as medium and long-distance wireless communication equipment.
