1 Introduction

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.

2 Hardware Spec

  • Ultra-low out-of-band noise
  • Audio data bit length: 16-bit, 24-bit and 32-bit
  • Audio format selection: I2S (Low) / Left-justified
  • Sampling frequency: 384KHz, resolution: 32-bit
  • Onboard infrared receiver

4 使用方法

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。
