PAM8403 5V Two-channel Stereo Mini Class-D 3W+3W Audio Amplifier
SKU: MISC-1100224 in stock
The PAM8403 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.

MP3-TF-16P MP3 Disk TF Card Module
It’s a small and low-cost MP3 module player with a simplified output directly to the speaker. It can be used as a stand-alone module with an attached battery, speaker, and push buttons or used in combination with an Arduino UNO or any other with RX/TX capabilities.This perfectly integrates the hard decoding module, which supports common audio formats such as MP3, WAV, and WMA. Besides, this module also supports TF card with FAT16, FAT32 file system. Through a simple serial port, you can play the designated music without any other tedious underlying operations.SKU: MISC-11001
