Raspberry Pi Rack Mount with status indicator LED and power/shutdown button at front panel

Description

I designed a Raspberry Pi server rack mount with up to two status indicator LEDs and power/shutdown button at front panel. It does allow to mount up to two Raspberry Pi in a 10" server rack in 1U height (one on the left, a second one on the right). In addition I designed a tiny PCB to add up to two status indicator LEDs and a power/shutdown button at the front panel to easily power (or shutdown) your pi while it is mounted in a server rack. In addition this PCB allows to connect a cooling fan and necessary electronics (transistor etc). <h2>Bill of materials:</h2> - 1x Raspberry Pi 3B+ - 1x Fan (3x3 cm) like this one: https://www.amazon.de/dp/B00UWIB68U - 1x NPN Transistor - 1-2x LED 3mm (any colour) + protective resistor - 1x Button like these ones: https://www.amazon.de/dp/B00D82M9LA - optional self designed front panel PCB for easy access while mounted in a server rack. (I did order some more than I do need for myself and am happy to send those out. Just drop me a message...). - some wires <h2>This is how you need to wire everything up:</h2> <table> <tr> <td>Pi Header PIN</td> <td>Front panel PCB</td> <td>Colour in Picture</td> </tr> <tr> <td>4 (+5V)</td> <td>FAN Ctr: PWR FAN</td> <td>pink</td> </tr> <tr> <td>5 (GPIO 3)</td> <td>BTN: BTN</td> <td>grey</td> </tr> <tr> <td>6 (GND)</td> <td>LED: GND</td> <td>blue</td> </tr> <tr> <td>8 (GPIO 14)</td> <td>LED: LED 1</td> <td>yellow</td> </tr> <tr> <td>9 (GND)</td> <td>BTN: GND</td> <td>black</td> </tr> <tr> <td>12 (GPIO 18)</td> <td>FAN Ctr: IO</td> <td>white</td> </tr> </table> To use the button as a power button follow this instruction: https://howchoo.com/g/mwnlytk3zmm/how-to-add-a-power-button-to-your-raspberry-pi If you want the LED function as a status LED you need to make some adjustment to your pi. Edit your /boot/config.txt file and add the following line: "enable_uart=1".
