The OnOff SHIM from Pimorino allows you to savely start and shutdown your Raspberry Pi through a button. While you can switch of your Phoniebox via an RFID Card (through an RPC command), it is difficult to switch it on again without cutting the physical power supply.
To install the software, open a terminal and type the following command to run the one-line-installer. A reboot will be required once the installation is finished.
Note
The installation will ask you a few questions. You can safely answer with the default response.

| Board pin name | Board pin | Physical RPi pin | RPi pin name |
|---|---|---|---|
| 3.3V | 1 | 1, 17 | 3V3 power |
| 5V | 2 | 2 | 5V power |
| 5V | 4 | 4 | 5V power |
| GND | 6 | 6, 9, 20, 25 | Ground |
| GPLCLK0 | 7 | 7 | GPIO4 |
