How to assemble our TV HAT Case for Raspberry Pi 4!
Please note images in this guide are for the previous version of the TV HAT case (updating very soon!) but the overall assembly is the same.
What you need
!! Important note!! - At step 4, It's best to attach the GPIO header to the HAT before fitting to the Raspberry Pi. It keeps the pins fitted properly inside the HAT for a solid connection.
1. The laser-cut parts of the case are protected by an adhesive film which needs to be removed before assembly (this is *very* therapeutic), simply peel it off
2. Using the black screws, attach the 5mm m/f stand-offs to the bottom plate of the case (this kit also uses 6mm m/f stand-offs, so make sure you're using the 4 shorter ones!)
3. Place your Raspberry Pi 4 Model B on top of these stand-offs with the SD card above the SD cutout and attach the 12mm f/f standoffs on the GPIO side and longer 20mm f/f standoffs on the opposite side. Be careful not to over-tighten as this could damage the acrylic.
4. Fit the GPIO header (which came with your TV HAT) to the HAT itself (not the Pi). This is to ensure the HAT has a good connection with the header, as the kit standoffs are taller than the originals.
5. Now add your Raspberry Pi TV HAT on top, followed by two 6mm m/f stand-offs (upside down this time) to both sides of the TV Hat.
You will notice a small gap between the Pi and the header - this is expected and doesn't impact the connection/performance.
6. Assembling the side pieces is nice and easy - they'll be loose at first, but don't worry, the lid and screws on top hold the case together nice and snug.
7. Close the case and screw it shut with the remaining black screws.
Viola! Case complete!
NOTE: Acrylic is a hard and stiff plastic which is sensitive to stress concentrations and shares a certain level of fragility with glass. Acrylic can scratch easily and should be cleaned with a mild solution of dish detergent and warm water. Never use cleaners unsuitable for acrylic. Never use a dry, abrasive cloth.
