Ebyte EWM628-2G4T20SX SX1281 2.4GHz 20dBm LoRa Full-Duplex Wireless Transmission Module – 3.5km Communication Distance
The EWM628-2G4T20SX is a new-generation LoRa wireless full-duplex automatic frequency-hopping data transmission module with a transmit power of 20dBm. It supports multiple transmission modes and operates in the 2.4GHz ISM band, using LoRa spread-spectrum wireless transmission technology. It features TTL level output and is compatible with 3.3V IO port voltage. With higher speed, lower power consumption, and a smaller footprint, it supports full-duplex frequency-hopping transmission, carrier sensing, automatic relay, communication encryption keys, and other functions.
