Want to increase the audio output capability of your project? Well then this is the perfect module for you. This module is based on famous TDA2030 Audio Amplifier Module which is capable of 18 watt power output with very low harmonic distortion.
Specification of TDA2030 Audio Amplifier Module:-

• On board TDA2030A Audio amplifier Board
• Mono channel 18W Power amplifier circuit design
• On board horn socket
• On board 10 k adjustable resistance, can adjust the volume of the amplification
• On board power indicator light
• Chip has lead to the main pin, can directly input audio signal
• Working voltage:6-12V
• PCB size:32(mm)x24(mm)

This Audio Amplifier Module is based on PAM8403 which is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area.With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications.  Features of PAM8403 Module:-

• Dual channel stereo output 3 w + 3 w power Class D
• Works with 2.5V-5v power supply
• High amplification efficiency 85%
• can directly drive 4 O/8 O small speakers
• Good sound quality  & noise suppression
• Unique without LC filter class D digital power board
• Can use computer USB power supply directly
• Small Size, 1.85 x 2.11 cm   can easily fit in a variety of products

Note when using:-

• Input audio should be via shielded wire for best performance.
• Use proper filtered power supply with good filter capacitors.
• Take care not to short speaker wires else IC will get damaged.
• Make sure power supply never execeds 5.5V else IC will get damaged. Use regulated power supply.

This is PAM8403 Mini 5V Digital Amplifier Board With Switch Potentiometer. PAM8403 is a small digital amplifier chip, high-definition sound quality highlights the advantages of digital chips, the circuit using the most reasonable peripheral configuration, power supply filtering is upgraded to 470uf (some sellers are less did not even 100uf capacitance).

1.6mm glass sheet, the real amplifier board did the most detailed, high-fidelity sound output 3W + 3W, is a rare good product enthusiasts amplifier, potentiometer using the original anti-meter body, potentiometer with the switch can cut off the power supply directly counterclockwise.

Usage:
Suitable for battery or portable electronics products, suitable for long time steady usage.

Note!!!
Please make sure the power supply is not more than 5.5V and please don’t do reverse polarity for “+” and “-“, or else, it will burn the board. 

Features :

1. PCB size is about: length 30mm width 22mm overall height after installed is about 16mm
2. Built with switch Potentiometer, can adjust the volume & control power switch freely!
3. Flexible assembly usage.

Package Includes :

1 x PAM8403 Mini 5V Digital Amplifier Board
