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。
