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.

4 Applications
The NanoHat PCM5102A can be stacked on supported boards. Here is a hardware setup:
5 How to Play
5.1 Under H3 & Linux-3.4 Kernel
If you use a FriendlyElec's H3 board under Allwinner's released Linux-3.4 kernel run the following command to check whether or not the NanoHat PCM5102A is enabled:
$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Pcm5102a [Pcm5102a], device 0: Playback pcm5102a-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sndhdmi [sndhdmi], device 0: SUNXI-HDMIAUDIO sndhdmi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0
card 0 stands for pcm5102a. You can play an audio file by running the following command:
$ aplay /root/Music/test.wav -D plughw:0
-D plughw:0 stands for audio card 0. Connect your module to a speaker and you will hear your music.
5.2 Under H3/H5 & Linux-4.x Kernel
If you use a FriendlyElec's H3/H5 board under Allwinner's released Linux-4.x kernel you need to enable the NanoHat PCM5102A with npi-config:
Start npi-config as root:
$ npi-configOpen the following menu:
Open I2S:
Enable/Disable I2S. By default I2S0 is disabled:
After you enable I2S0 I2C1 will be disabled.After I2S0 is enabled select pcm5102a:
Return to the main menu and do <Finish>. Reboot your system and run the following command to check whether or not the NanoHat PCM5102A is enabled:
$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sndsun8ii2sdac [snd-sun8i-i2s-dac], device 0: sun8i-i2s-dac pcm5102a-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Codec [H3 Audio Codec], device 0: CDC PCM Codec-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0
card 0 stands for pcm5102a. You can play an audio file by running the following command:
$ aplay /root/Music/test.wav -D plughw:0
-D plughw:0 stands for audio card 0. Connect your module to a speaker and you will hear your music.
