Product Descriptions
E22-170M30S is a self-developed ultra small size based on the new generation LoRaTM RF chip SX1262, and is suitable for 170.125MHz surface mount LoRa wireless modules. Due to the use of the original imported SX1262 as the module core, the anti-interference performance and communication distance have been further improved compared to the previous generation LoRaTM transceiver. Due to its adoption of the new LoRaTM modulation technology, its anti-interference performance and communication distance far exceed those of current FSK and GFSK modulation methods. This LoRa module is mainly designed for smart homes, wireless meter reading, scientific research and medical, as well as long-distance wireless communication devices.
