NanoHat PCM5102A

The Matrix - NanoHat PCM5102A module uses TI's DAC audio chip PCM5102A and NS' low-noise, ultra-low dropout LP2992 regulator. PCM5102A's sample rates up to 384kHz and its resolution is 32-bit.
Its dynamic range is 112dB. Its THD+N at –1 dBFS is -93db. Its full-scale single-ended output is 2.1V. The SNR is 120dB.
Its onboard VS1838B infrared receiver allows it to be remote-controlled.
This module has exactly the same dimension as the NanoPi NEO/Air and can be stacked on an NanoPi NEO/Air.

NanoHat PCM5102A可直接叠加在NanoPi NEO/Air上。参考下图连接模块：

按照上述硬件连接方法把模块堆叠在NanoPi NEO/Air上，使用最新的ROM制作SD启动卡，并连接电源和音响，3.5mm接口的音响可以使用3.5mm接口转RCA口音频接线转接。

使用以下命令播放TF卡里的音乐文件，以kewang.mp3为例。

madplay kewang.mp3

播放效果如下：
