1 Introduction
- The 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.

The NanoHat PCM5102A can be stacked on supported boards. Here is a hardware setup:
5 How to Play
After you mount your PCM5102A to a NanoPi NEO/Air connect your PCM5102A to speakers with a RCA to 3.5mm audio jack cable and power on your NanoPi NEO/Air
Run the following commands to play an audio file (in our example we played kewang.mp3)
madplay kewang.mp3
