At present, our domestic audio industry Due to these key components, it is still difficult to make a sound.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\n\u003cspan style=\"font-family: microsoft yahei;\"\u003e\u003cspan style=\"font-size: 24.0px;\"\u003eBut on the market level, the two are different for DIY. LM1875 has a large playability space and a small space.

This module accounts for a large proportion in the market, but DIY restrictions cannot be achieved. Under the requirements of many burners, this STK4 ** 1 general-purpose power amplifier board has been developed, which can be compatible with a variety of modules and is easy to use.
