It can amplify the small audio signal output, about 8.5 times magnification, and can play it out via a small power speaker. Pay close attention that should adjust the sound volume to a minimum before use, then slowly increase the speaker volume, preventing from burning the speaker. When testing, after connected to microcontroller, input square waves.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSKU: KS0374\u003c\/li\u003e\n\u003cli\u003eAmplifier chip: SC8002B\u003c\/li\u003e\n\u003cli\u003eOperating voltage: DC 5V\u003c\/li\u003e\n\u003cli\u003eOperating current: ≥500MA\u003c\/li\u003e\n\u003cli\u003eMaximum power: 2W\u003c\/li\u003e\n\u003cli\u003eOperating temperature: 0-40°\u003c\/li\u003e\n\u003cli\u003eSpeaker power: 0.15W\u003c\/li\u003e\n\u003cli\u003eSpeaker sound volume: 80db\u003c\/li\u003e\n\u003cli\u003eProperty: ROHS\u003c\/li\u003e\n\u003cli\u003eDimensions: 47mm * 30mm * 13mm\u003c\/li\u003e\n\u003cli\u003eWeight: 8.4g\u003c\/li\u003e\n\u003cli\u003eNote: 4.
