2. רעדנער קשר:

   Connect a 4Ω 3W speaker to the SP+ and SP- terminals. The module features solderless speaker terminals for easy wiring. Ensure the speaker impedance matches the recommendation for optimal performance and to prevent damage.

   

   Figure 3: This image focuses on the audio output section, displaying the screw terminals for speaker connection (SP+ and SP-) and the 3.5mm headphone jack. These are the primary audio output interfaces.
3. Audio Source Insertion:

   Insert a TF card (micro SD card) with MP3 files into the TF card slot, or connect a USB flash drive (U disk) with MP3 files to the USB-A port. The module will prioritize TF card playback if both are present.
