4. Setup jeung Instalasi
4.1. Integrasi Modul
The E220-400M30S module comes in an SMD (Surface Mount Device) package, designed for integration onto a PCB. Ensure proper soldering techniques are used to avoid damage to the module. The module's pins are spaced at 2.54mm for easy connection.
4.2. Power Supply
Provide a stable power supply between 3.0V and 5.5V. A typical operating voltage of 5V is recommended to ensure optimal output power. Using a 5V TTL communication level is risky and may damage the module; ensure your communication level matches the module's 3.3V.
4.3. Antenna Selection
The module offers two antenna options:
- IPEX Antenna Interface: For connecting an external antenna. This is suitable for applications requiring increased transmission distance.
- Stamp Hole Antenna: A built-in antenna option, easier to integrate and suitable for most general requirements.
Note: Only one antenna type can be selected and used at a time.

4.4. Interface Komunikasi
The module uses an SPI (Serial Peripheral Interface) for communication. Ensure your host microcontroller is configured to communicate via SPI at speeds between 0-10Mbps.
