🔊 What Does It Do?

The amplifier kit combines a stereo high-power amplifier with a Bluetooth 5.0 MP3 module, making it an excellent project for:

• Learning about signal amplification and circuit design

• Exploring Bluetooth wireless audio

• Building a DIY stereo system

It includes treble, bass, and volume controls, with each channel capable of delivering up to 6W into a 4Ω speaker.

🧰 What’s Inside the Kit?

The kit is packed with everything required to build a working amplifier:

• Stereo Power Amplifier PCB

• TDA1519 Amplifier IC (dual 4W amp)

• LM324 IC

• Bluetooth 5.0 Module (ARD2-2049)

• Resistors, capacitors, zener diodes, LED indicator

• 3.5mm line-in stereo socket

• Heatsink, screws, slide switch, potentiometers

These components give students real hands-on experience with electronics assembly, while also creating a practical end-product.

🔧 Building the Amplifier

The construction process teaches electronics assembly skills:

1. Start with low-profile components (resistors, capacitors, LEDs).

2. Mount the TDA1519 IC with heatsink for safe heat dissipation.

3. Fit the Bluetooth module after testing the main circuit.

4. Use soldering techniques and double-check polarities.

Students learn not just how to assemble, but also why each component matters in the overall design.

📡 Bluetooth & Testing

Once assembled, the Bluetooth module allows users to stream music wirelessly. Testing steps include:

• Power on with a 12V DC supply

• Green LED confirms amplifier readiness

• Blue LED confirms Bluetooth pairing

• Line-in option via the 3.5mm stereo socket (overrides Bluetooth)

This dual-input feature makes it flexible for both modern and traditional setups.
