EByte E32-900T30D LoRa Module 868/915MHz SX1276 30dBm 1W

Configuration is performed via a dedicated UART configuration interface using specific AT-style commands sent at a fixed 9600 baud rate. You must connect the module's MD0 pin to a GPIO for mode selection, placing it in configuration mode to set frequency, transmit power, air data rate, and other parameters. Detailed command sets are available in the EByte datasheet.

The module's serial interface operates at 3.3V TTL logic levels. You must connect its TXD and RXD pins to a 3.3V UART port on your microcontroller (e.g., ESP32, STM32, Arduino Pro Mini 3.3V). Applying 5V TTL signals can damage the module. Ensure your host system's logic voltage is 3.3V or use a bidirectional logic level converter for safe interfacing with 5V Arduino boards.

Use a 50-ohm antenna tuned for the 868MHz or 915MHz band, such as a whip or dipole, with a gain appropriate for your application. The module features an integrated plug-in (spring-loaded) connector. Carefully mate the antenna's pin connector with this socket. For optimal range and to comply with regulatory limits, ensure the antenna is impedance-matched and has an appropriate VSWR for the selected frequency.

While the underlying SX1276 chip supports LoRa modulation, this specific E32 module is typically firmware-configured for simple point-to-point or transparent serial transmission. To use it with LoRaWAN, you would need to implement a LoRaWAN stack (e.g., LMIC, LoRaMac-node) on an external microcontroller that uses the module as a radio via SPI, not its built-in UART. It is not a plug-and-play LoRaWAN node module out of the box.
