Ebyte E22-230T33E sx1262 33dBm12km UART/RS485/RS232/USB interface Fast long-distance transmission lora transparent module

[Chip solution]:SX1262

[Carrier frequency]:220.125~236.125 MHz

[Transmission power]:33dBm

[Communication distance]:12km

[Introduction]:E22-230T33E is a new generation of LoRa wireless spread spectrum module, a wireless serial port module designed based on SEMTECH's SX1262 chip solution. It has a variety of transmission methods, works in the 220.125-236.125MHz frequency band, is compatible with 3.3V and 5V IO port voltages, adopts MINI PCI-e standard packaging, and has UART/RS485/RS232/USB communication interface options, which is convenient for users to develop and use. Using a new generation of LoRa spread spectrum technology, this solution has a longer transmission distance and faster speed; supports air wake-up, wireless configuration, carrier monitoring, automatic relay, communication key and other functions, supports packet length setting, and can provide customized development Serve.
