The Hat SPK is a speaker that works great with M5StickC. It comes with an integrated PAM8303 amplifier, a 3w single channel type D power amplifier. With high PSRR and differential inputs, it can effectively get rid of noise and RF interference, providing simple functions and high - quality audio reproduction. Product features include ultra - low EMI interference (20dB better than FCC class B standard at 300MHz), a 5V voltage power supply that can output 3w with a 4Ω load and 10% total harmonic distortion, ultra - low noise when there's no input, a power range from 2.8V to 5.5V, and shortcut protection. The package includes 1x SPK Hat. It's suitable for MP4/MP3. You can learn more from the schematic, official channel, official forum, and PAM8303 Datasheet. There's also an Arduino example available.




Using this M5StickC compatible speaker hat is easy. First, connect it to your M5StickC device. Make sure to use a power supply within the 2.8V - 5.5V range to ensure proper operation. When using it with MP4 or MP3 players, just plug it in and you'll start getting great audio. Remember, this speaker hat has shortcut protection, but still avoid short - circuiting it intentionally. For maintenance, keep it in a dry and clean place. If it gets dirty, use a soft, dry cloth to gently wipe it. Don't expose it to extreme temperatures or moisture, as this can damage the internal components.
