⚠️ Critical Important Notes

⚠️ Voltage: The module operates on 3.3V ONLY. Connecting to 5V will permanently damage it .
⚠️ Power Supply: The module draws up to 115mA during transmission. The Arduino 3.3V pin cannot supply this current. Use an external 3.3V regulator (e.g., AMS1117-3.3) .
⚠️ 10µF Capacitor: It is highly recommended to add a 10µF capacitor between VCC and GND near the module to stabilize the power supply .
⚠️ Line of Sight: Maximum range requires a clear line of sight. Avoid metal obstacles and sources of interference .
