[Introduction]:E32-400T20S-V2 is a wireless serial port module developed for the wireless meter reading industry. The factory default is 470MHz meter reading frequency band, long packet mode (197 bytes per packet) and the module supports LoRa™ spread spectrum technology. The LoRa spread spectrum solution has the characteristics of air wake-up function (low power consumption), long communication distance, anti-interference ability and strong confidentiality. It uses industrial-grade crystal oscillators to ensure its stability and consistency, and the accuracy is less than 10ppm commonly used in the industry.
