6. Setup jeung Instalasi

6.1 Sambungan Power Supply

Connect the module to a stable power supply within the 2.2V to 3.8V range. For optimal performance and stability, a power supply of 3.3V or higher is recommended. Ensure correct polarity (VCC and GND pins) to prevent damage to the module.

6.2 Sambungan anteneu

Attach a suitable 433MHz antenna to the IPEX connector on the module. For best range and signal integrity, ensure the antenna is correctly matched and positioned away from metallic obstructions. If using the stamp hole option, ensure proper soldering for antenna connection.

6.3 UART/IO Interface Connection

Connect the module's UART (Universal Asynchronous Receiver/Transmitter) pins (TXD, RXD) to your host microcontroller or system. The IO port voltage is 3.3V. Ensure proper level shifting if your host system operates at a different voltage (e.g., 5V) to avoid damaging the module.

6.4 Konfigurasi Parangkat Lunak

The module comes with a pre-programmed low-power multifunctional wireless serial program. Users can configure parameters such as frequency, transmission power, and air data rate via serial commands. For advanced functionalities or custom applications, secondary development using the CC1310's capabilities is supported.

7. Parentah Operasi

7.1 Data Transmission and Reception

Once properly configured, the module can transmit and receive data wirelessly. Data sent to the module's UART TXD pin will be transmitted over the air, and data received wirelessly will be output via the UART RXD pin. Ensure that both transmitting and receiving modules are configured with compatible parameters (frequency, air data rate, etc.).

7.2 Forward Error Correction (FEC)

The integrated FEC algorithm automatically adds redundant data to transmissions, allowing the receiver to detect and correct certain errors that may occur due to interference or signal degradation. This feature improves the reliability and effective range of communication, especially in noisy environments. No direct user intervention is typically required for FEC operation.

7.3 Low Power Operation

The E70-433T14S is designed for low power consumption, making it suitable for battery-powered devices. Utilize the module's low-power modes and air wake functionality to minimize energy usage in applications where continuous operation is not required. Refer to the detailed CC1310 datasheet and EBYTE's programming guide for specific low-power mode configurations.
