When I use it without the amplifier ("audio no amp. 2 x PAM8403 Ultra Miniature Digital Power Amplifier Board Class D 2channel x 3W. see sound testing video here. The PAM8403 is available in SOP-16 package. The "low noise" was not as low as I had hoped and produced an intolerable hissing that irritated me enough to toss them into the trash. So I used PAM8403 ("audio. The 7805 is an outdated regulator, so better buy a 2 ampere USB car charger, it's much more effecient compared to having two 7805s. They cost only a dollar or two on eBay, are easy to use, and have great sound and specs. The PAM8403 is a 3W, class-D audio amplifier. Attention ! Both "minus" outputs SHOULD NOT BE CONECTED TOGETHER (for example for headphone output) because it will damage the chip. When working with a 5v power supply it can directly drive 4 Ω/8 Ω small speakers with big output power and good sound quality. Cheap audio amplifier board, Buy Quality audio module directly from China bluetooth stereo board Suppliers: Pure Bluetooth 4. First we should say that ICStation doesn't accept any form of pay on delivery. 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. This miniature PAM8403 module is a 3W, class-D stereo audio amplifier.
