Digital Amplifier Board 2x3W Class D PAM8403
Excellent noise suppression, in the absence of circumstances connected to input audio ear close to the speaker cannot hear any noise, two-channel stereo, 5V power supply can output 3W power, can directly drive 4Ω, 8Ω small speakers, the output power large, full of energy, good sound quality. The unique non-LC filter Class-D digital power board can be directly used computer USB power supply. Double panel wiring, wiring properly resolve the ground potential caused by balance and inter-channel crosstalk, ultra-miniature design, can easily be placed in a variety of digital products within a small space, high amplification efficiency. All using the whole plate welding machine, welding quality comparable non-manual soldering iron!
– Advanced Micro Devices, volume: 1.85 * 2.11cm
Excellent noise suppression in the case is not connected to the input audio, the ear close to the speaker cannot hear any noise
