In this article, we will show you how to assemble the black steel case by HiFiBerry for the AMP2 with Raspberry Pi 4B.
At the beginning, the Raspberry Pi is inserted into the base plate. The base plate can be recognized by the cutouts for the USB connections and the LAN connection. Use the four short round-head screws to attach the Pi to the case.
Now attach the spacers to the HiFiBerry AMP2 as shown in the picture. Use the four nuts as counterparts.
Now the sound card is inserted into the cover plate so that the sound outputs fit into the recesses provided. Now screw the short countersunk screws from above into the spacers, which are attached to the sound card.
Then you can put the two case parts together. Careful with the GPIO pins of the Raspberry Pi! They have to fit exactly into the GPIO slot on the sound card. Do not exert too much pressure, try to bring both case parts together in a centered manner and pay particular attention to the 3.5mm jack connection of the Pi.
If everything fits, the connections of the Pi should snap into the recesses of the case.
