Wire Wound Inductor: From Germany Wurth, ensuring high Q value and low attenuation.
LNA: Baixo ruído Amplifier, improving receiving sensitivity.
PCB: 4-layer PCB design for improved EMC performance.

4.2 Instalación física

The E32-915T30D is a UART DIP module. It is designed for easy integration into your circuit board. Ensure proper pin alignment when inserting the module into a DIP socket or soldering it directly.

Installation Accessories: Nuts and Washers — Figure 5: Included Installation Accessories. The module comes with factory nuts and washers, which are beneficial for secure installation, especially for the SMA connector.

For securing the SMA antenna connector, utilize the provided nuts and washers to ensure a stable and reliable connection. This prevents loosening and maintains signal integrity.

4.3 Conexión á fonte de alimentación

Connect the module to a stable power supply within the range of 3.3V to 5.2V. A 5.0V supply is recommended for optimal performance. Ensure correct polarity to prevent damage to the module.

4.4 UART Interface Connection

Connect the module's UART pins (TX, RX, GND, VCC) to your microcontroller or host system. Ensure that the UART baud rate and other parameters are correctly configured on both the module and the host device for proper communication.

5. Operating Modes and Data Transmission

The E32-915T30D module supports various data transmission modes to suit different application requirements.

5.1 Transparent Transmission (Point-to-Point)

In this mode, data is sent transparently between two modules. Both modules (Module A and Module B) must have the same address and channel configured. Data sent by one module is received directly by the other, acting as a simple wireless serial link.

5.2 Transparent Transmission (Broadcasting)

Each module can act as a transmitter to send out data to multiple receivers. In this mode, a single transmitting module sends data that can be received by any other module within range, regardless of their specific address, as long as they are on the same channel.

5.3 Broadcast 0xFFFF Transmission

To broadcast data to all modules on a target channel, set the sending address to 0xFFFF. This allows a single module to transmit data that will be received by every module configured for that specific channel, enabling a one-to-many communication setup.

5.4 Fixed Transmission

This mode allows each module to connect with other modules in different addresses and channels. This is useful for more complex network applications, such as repeating or routing data, where specific modules need to communicate with designated partners across different network segments.
