Music plays on a [Raspberry Pi](https://www.raspberrypi.com/products/raspberry-pi-4-model-b/) which cost £36 and an [IQAudio DigiAmp+ board](https://www.raspberrypi.com/products/iqaudio-digiamp-plus/) which cost £30. This device runs [piCorePlayer](https://docs.picoreplayer.org/getting-started/) which runs as an LMS client. The device also has a rotary encoder (KY-040), 128X64 Pixel OLED display (SSD1306) and an IR receiver (TSOP38238) which I use with an old apple remote. This is a pretty nice little Class D amplifier, running full-HD 192kHz / 24bit audio at 2x35w, which powers a set of Wharfedale 9.1 speakers I picked up used for £50.
- You can find a useful pinout reference for this board [here](https://pinout.xyz/pinout/pi_digiamp#).
- You can find instructions on adding in an IR receiver via [piCorePlayer documentation](https://docs.picoreplayer.org/projects/add-an-ir-receiver/) and also a useful blog post [here](https://smarthome.exposed/infrared-remote-for-hifiberry/). If you're using an apple remote like I am, you'll need to upload the custom `lircd.conf-A1156` file which I've included in this repository.
- Note: I've tried running this device using [Volumio 3](https://volumio.com/en/volumio-3) and [Mopidy](https://mopidy.com/) (in June-July 2022). I found both of these platforms to be overly complex and unstable as music players so eventually settled on LMS friendly piCorePlayer. I have never experienced any performance problems with this platform, which streams FLAC files over wifi without any difficulties.
