[Passed by actual test] Jerry AC1082 main control high-quality audio decoding board

introduce:

High-quality sound decoding AC1082, supports TF card reading and U disk reading. Equipped with TP4056 lithium battery charging IC. Adopts 1S lithium battery power supply mechanism. Dual-channel stereo high-quality audio output. The buttons are fully functional and can be controlled to switch reading mode (TF/U disk) control. Volume, free to switch songs and pause, affordable BOM cost

This solution is based on the design of the finished AC1082 sold on Taobao. The code is burned by the seller. This project does not contain code, and I can’t write code. However, most of Taobao’s AC1082 solutions are this kind of peripherals, which are basically purchased on Taobao. The AC1082 that has been programmed can be directly operated on this board. Except for the difference in the button voltage dividing resistors of some merchants, the peripherals are all like this.

It is equipped with a 24C02 to store the second-level memory of song playback progress. The next time it is powered on, it can locate the last playback position in seconds. According to this feature, there is no need to install the pause button, and it starts up very quickly, 128G You can also make a sound within one second. If this memory chip is not soldered, the playback progress can only be located to the last played song, but the quick start is still not affected. In addition, the memory card also supports the EXFAT format, so the compatibility is quite good. There are some shortcomings: it does not support lossless decoding such as FLAC APE, but it can be transcoded to WAV format, so that you can listen to lossless music without compromising the sound quality.
