EBYTE E220-900T22D LLCC68 LoRa Module

The EBYTE E220-900T22D LoRa communication module is an advanced solution for long-range wireless data transmission, operating in the 868–915 MHz band. The use of LoRa technology ensures stable communication even in challenging conditions, such as dense urban areas or environments with high levels of radio interference. The module is compatible with ESP8266, ESP32, Arduino, and Raspberry Pi.

It stands out for its significantly greater range and higher resistance to interference compared to standard radio modules, while maintaining very low power consumption. Communication takes place via a UART (TTL) interface, which simplifies integration without the need to implement the LoRa stack yourself.
