The E220-900T22D is a high quality LoRa wireless module from EBYTE, including a 915MHz folding antenna. It has a UART interface. It operates at 850.125MHz to 930.125MHz, and integrates an original LLCC68 chip from SEMTECH.

It has multiple transmission modes. It complies with FCC standards and meets various RF certification requirements. It is widely used in IoT applications, utility meters, smart home, etc.

The LLCC68 chip can NOT be accessed via the chip's SPI port. This module has a built in controller taking care of all the complex LLCC68 setup and interfacing, allowing communication via a simple UART(at 3.3V TTL signal levels).

These modules are designed and manufactured with quality in mind. High quality capacitors and German Wurth wire wound inductors are used. A temperature compensated crystal oscillator is used for timing, which is critical for low error long distance LoRa communication.
