Opsætningsvejledning

1. Strømtilslutning:

   Connect the power supply to the module. You can use a 3.7V lithium battery, a 5V USB power supply via the MicroUSB port, or direct 3.7V-5.5V DC input to the BAT+ and BAT- terminals. Ensure correct polarity.

2. Højttalerforbindelse:

   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.

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.
