The E32-900T20D is a high quality LoRa wireless module from EBYTE, including a 915MHz folding antenna. It has a UART interface. It operates at 862MHz to 931MHz, and integrates an original SX1276 chip from SEMTECH.
It has multiple transmission modes. It complies with FCC, CE and CCC standards and meets various RF certification requirements. It is widely used in IoT applications, utility meters, smart home, etc.
The SX1276 chip can NOT be accessed via the chip's SPI port. This module has a built in controller taking care of all the complex SX1276 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.
