4.2. കണക്ഷനുകൾ
- വൈദ്യുതി വിതരണം: Connect a stable DC power source to the designated power input pins. Ensure the voltage is within the module's specified operating range (typically 3V-5V, refer to datasheet for exact values).
- ആൻ്റിന: Connect an appropriate FM antenna to the antenna input. A simple wire can often suffice for basic reception, but a dedicated FM antenna will improve signal quality.
- ഓഡിയോ ഔട്ട്പുട്ട്: Connect headphones or an amplifier to the audio output jack (typically a 3.5mm stereo jack). The module provides two-channel stereo audio.
- നിയന്ത്രണ ബട്ടണുകൾ: The module features integrated push buttons for control. These are typically for power, volume adjustment, and station tuning.
