RaspyPlay4 is a high-fidelity audio board for Raspberry Pi A+, B+ or Model 2. It sheds concerns regarding its looks and branding; it's all about function. Stripped to the bare essentials, the RaspyPlay4 focuses solely on delivering you the best audio experience you can have on a budget.
- PCM5122 DAC
- Two standard RCA stereo audio connectors
- 3.5mm line-out connector
- TSOP34836 IR receiver footprint, for remote control
- Hardware volume control (24 dB to -103 dB)
- SNR: 112 dB
- Dynamic Range: 112 dB
- THD+N @ -1 dBFS: –93 dB
- Full Scale Output 2.1VRMS (GND center)
- Sampling Frequency 8 to 384 kHz
That's not all; the devil is in the details. For example, the System clock (MCLK) is generated by PLL which is integrated in the DAC chip, reducing high-frequency electromagnetic interference, which further improves the audio experience.
Then there's the ultra-low-noise voltage regulator, the hardware volume control, the footprint where you can add an IR receiver for remote control, and a 2×5 connector for an optional LCD.
Its biggest feature will be your music library. You can play your music on RaspyPlay4 from a USB flash, a USB hard drive, an SD Card, a NAS server, or even stream it through AirPlay, or any other web radio. Supported formats are FLAC, ALAC, mp3 and WMA.
RaspyPlay4 Software There are many software solutions that can work with your Raspberry Pi A+/B+/2B and RaspyPlay4 setup. RuneAudio is recommended. This popular open-source multi-platform music player software is the easiest to use because it already has built-in support for RaspyPlay4. It also has a convenient web interface allowing you to control playback from any number of devices.
Alternatively, you might also consider Volumio, another free Hi-Fi Audio player compatible with the RPi.
The RaspyPlay4 board ships with one 4-pin male header that can be used to populate the UART interface, and one 2×5-pin dual-row male header that can be used to populate the LCD interface.
