Opis Steel case for HiFiBerry Digi, Pi 4, V2 Compatible with: Raspberry Pi 4 & Digi+, Digi2 EAN/GTIN: 4260439550736 This is our most robust case. Made completely from steel, it also looks very nice. If you don’t like plastic, this is the case you should choose. Description This is our most robust case. Made completely from steel, it’s durable and looks very nice. The new version 2 of the case also allows to use it with the Digi+ I/O. ASSEMBLING THE NEW STEEL CASE STEP 1: PREPARE THE CASE If you’re using the DAC+ ADC, you need to break out the lid that covers the hole for the phone jack. A small pair of pliers will help you removing this. If you’re using a standard DAC+ without the phone jack, you don’t need to do anything. STEP 2: MOUNT THE RASPBERRY PI TO THE BASE While you can use all 4 screws, it will be already robust enough if you fix the Pi with two screws, STEP 3: MOUNT THE SPACERS ONTO THE HIFIBERRY DAC+ STEP 4: MOUNT THE HIFIBERRY DAC+ ONTO THE TOP OF THE CASE STEP 5: SNAP BOTH PARTS TOGETHER This step is a bit tricky. Make sure that top and base are aligned correctly. The HiFiBerry DAC+ should now slide into the 40 pin GPIO header. The 40 pin header and the phone jack on the Pi will ensure a stable connection between both case parts.
