| The Raspi-Sonic-Hat is a sound card for the [[https://www.raspberrypi.org/|Raspberry Pi]]. It is based on the [[https://www.cirrus.com/products/wm8731/|WM8731]] I2S sound chip by Cirrus Logic (former Wolfson). The board design is a hybrid of the [[https://statics.cirrus.com/pubs/proDatasheet/WM8731_v4.9.pdf|WM8731 datasheet]], the [[https://www.mikroe.com/audio-codec-proto-board|Audio Codec Board - PROTO]] and the [[http://www.audioinjector.net/rpi-hat|Audio Injector]]. That is why one can use the [[https://github.com/Audio-Injector/stereo-and-zero|Audio Injector software]].\\ | The Raspi-Sonic-Hat is a sound card for the [[https://www.raspberrypi.org/|Raspberry Pi]].
