I set upon a project of placing speaker pairs in most rooms of the house, with the ability to synchronize. My finished setup consists of a mix of Raspberry Pi 3 and 4, with HifiBerry Digi2 Pro hats, optical cables connecting to DACs, such as the Fosi Audio ZD3, XLR to amplifiers.
The enclosure provided here is designed to support a Raspberry Pi 4, with a passive heatsink. Openings in the sleeve portions of the case, fit an InnoMaker DAC HAT and a HifiBerry Digi2 Pro. Only the ports necessary for the Pi to function are exposed. Ports such as USB and HDMI are covered. When using a HifiBerry Digi2 Pro on a Raspberry Pi 4, I had trouble getting PiCorePlayer to recognize the HAT. After some research, I ended up using HifiBerry OS on that one and it worked just fine, integrated into the Sqeezelite ecosystem as any other player.
Parts needed:
(1) GPIO 2x20 Riser
(4) M2.5x4mm spacers
(12) M2.5x6mm or M2.5x8mm screws
Assembly Procedure:
1. Before inserting a MicroSD card, attach the Raspberry Pi 4 to the case bottom using 4mm thick M2.5 standoffs.
2. Install the GPIO 2x20 riser onto the GPIO header of the Pi. Do not install the HAT.
3. After deciding on the HAT to use, Digi or DAC, install the case bottom into the case sleeve, paying attention to the orientation. The MicroSD card slot, Micro USB power port and Ethernet port should line up. There is enough tension that you shouldn't need to attach the bottom and the sleeve with screws.
4. The sleeve has a pair of shelf tabs to support the free end of the HAT to be installed. Being careful to make sure that the GPIO pins line up correctly, press the HAT down onto the GPIO riser. The ports will rest on openings in the side of the case sleeve.
5. Using the correct lid, press the lid into place on top. The lid helps hold the outputs of the HAT in place, and also provide support to the back of each port to help prevent flexing when cables are installed. The lid fits a little loose, so may benefit from screws.
