Connect the module to your microcontroller or development board using the UART interface. Ensure correct voltage levels (3.3V or 5V) for the IO pins.

4.2 Antenneforbindelse

Attach a compatible 230MHz antenna to the SMA-K RF interface. Ensure the antenna is securely fastened for optimal performance.

4.3 Strømforsyning

Provide a stable power supply within the module's specified voltage range. Refer to the datasheet for exact power requirements.

5. Betjeningsvejledning

The E22-230T22D module operates via AT commands or through a dedicated configuration tool, depending on the firmware version.

5.1 Dataoverførsel

Once configured, data can be sent and received through the UART interface. The module handles the LoRa modulation and demodulation automatically.

5.2 Valg af tilstand

The module supports various operating modes, including transparent transmission, fixed-point transmission, and broadcast. Select the appropriate mode based on your application requirements.
