THE XPI PROJECT
I have created this page for my project called XPI – with a 3D printed box for Raspberry PI 4 and a self-made power supply management controller board called XPI. Check it out! The basics are 1: A 3D printed box. 2: A power management board to control power from and to the Raspberry PI 4. 3: Some cables. 4: A small computer with 1,2,4 or the lastest model with 8gb of ram.
THE XPI CABINET
The box I 3D-printed was with a 0.8mm nozzle -to get speed. The complete box is printed in 5 to 6 hours. I use a 0.8mm nozzle on my 3D printer (Ender 3 pro) so it can be printed fast. I use a height of 0.6mm and 0.8mm width. This complete 3 layers at 1.8mm height and 2.4mm width. The STL bundle has 2 master files that print top and bottom. These 2 files complete the XPI cabinet. I have also included all components I use, like SSD plate, RPI plate, connectors plate, etc. So you can adapt to your style or equipment. See documentation for more information about this.
THE POWER MANAGEMENT BOARD
Raspberry Pi 4 is a powerful microcomputer that, in my opinion, is underestimated, especially in what it can be used to. There are countless opportunities for smart boxes for everything – without the expensive cost.
Price is very important. When this is so low, it gives developers the opportunity to experiment extensively, without spending hundreds of dollars for a couple of models.
The stability of the Raspberry Pi 4 along with Raspberry Pi OS is impeccable good against Windows and Mac Os – which I use beside at the same time for my other work with computing. The principle is simple: first power the control bord (XPI Powerboard) then the Raspberry Pi 4. The power control board can tell Raspberry Pi ho shutdown and power of the system, and the Raspberry Pi can “tell” the controller board that it will turn itself off. Simple in principle.
The XPI Power Management Board are developed by (C) Morten Steenberg in 2020. The idea was from an old simple similar circuit board with very poor current support and to small transistors to support the load (current). The most circuit I have seen is made for Raspberry Pi Zero – a long time ago…
