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.
  • The SNR is 120dB.

模块信噪比112db,失真-93db,可直接输出2.1V RMS音频电压。模块软斜升或斜降搭配模拟静音,可实现120dB 静音信噪比(SNR)。

  • Its onboard VS1838B infrared receiver allows it to be remote-controlled.
  • NanoHat PCM5102A和NanoPi NEO/Air的外形尺寸和接口完全相同,可直接堆叠在NanoPi NEO或Air上。

2 特性

  • 超低带外噪声
  • 可接收 16、 24 和 32 位音频数据
  • PCM 数据样式: I2S, 左对齐
  • 采样率为384kHz,分辨率为32-Bit
  • 板载红外接收。

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。

madplay kewang.mp3

播放效果如下:
