Domipheus Labs posted part 2 of their series on building a wall mounted server based on Raspberry Pi. In this post, they detail taking apart the elements of the pi they won’t be using, creating a slimmer “diet Pi”.
The enclosure I’m using, a re-purposed room thermostat casing, places some very tight constraints on the dimensions of the Raspberry Pi and PiTFT board.The plastic used in the case is quite sturdy, and is at least 2mm in thickness. Therefore the real inner depth of the case is about 12mm. As for the width of the Pi, we need to shave at least 4mm from the side. The Pi itself is 86mm wide, same with the PiTFT board, so we will need to find a way of making it closer to 82mm.
The board interconnect that comes with the PiTFT is a tall terminal connector. It is immediately ruled out for use, as it increases the depth of the assembly to well over an inch. Without using that, and bending the pins to grip the I/O on the PiTFT, the depth from SD card housing to top of the TFT is just over 20mm. Still far too much.
The main space-wasters on the Pi are easy to identify. The composite out, audio out, USB, HDMI, and the camera and display interfaces all can be removed. The tallest of these, the Composite out, measures over 11mm alone. The only one we need to use is USB, and we can add terminals to enable an off-board connector for that. All the others need to go…

PiTFT Mini Kit – 320×240 2.8″ TFT+Touchscreen for Raspberry Pi: Is this not the cutest little display for the Raspberry Pi? It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! Read more.
