I ordered the following:
|1x||HiFiBerry Digi2 Pro|
|1x||Steel case for HiFiBerry Digi, Pi 4, V2 (Guide)|
|1x||Raspberry Pi 4B 2GB|
|1x||Heatsink for Pi CPU (Guide)|
|1x||SD card 32GB|
|1x||Raspberry Pi 4 power supply 5.1V/3A|
|1x||USB-C power switch|
Assembling was very easy.
Unfortunately I am struggeling the Heatsink installation as the link to the guide is incorrect: https://github.com/hifiberry/audiocontrol2/blob/master/doc/rotary-controller-plugin.md.
Any help is mucgh appreciated.
