On/Off Power Switch for Raspberry Pi
£12.50 ex VAT
The On/Off power switch by Pi Supply is the solution to all of your Raspberry Pi power management problems. It is an intelligent, ATX style power supply switch for the revolutionary Raspberry Pi computer. It allows you to leave all of the power wires from the wall wart all the way through to the Pi permanently connected with just the quick push of a switch to turn the power on or off. Simple!
In this kit you get a printed circuit board and all of the parts you need to put it together into a working unit, including a flat noodle USB cable to connect to your wall-wart power supply. Also includes a free sticker.
Note: This kit requires soldering.
HOW DOES IT WORK?
Once you have finished using your Raspberry Pi, you just shutdown using the sudo halt command, and then a couple of minutes after the full and safe shutdown the Pi Supply Switch cuts the power to the computer. From this point, once again, all you would need to do to restore power to the Pi is touch the on button.
There is also a hard power off button for use in emergencies which immediately cuts the power to your Raspberry Pi. Remember to only use this button when absolutely necessary (e.g. Pi has been frozen for a long time) as it risks corruption of the files on your SD card if done at the wrong moment.
What makes the switch superior to other makeshift solutions available is that it allows you to restart the Raspberry Pi using the sudo reboot command without the power turning itself off. Perfect!
PUTTING IT TOGETHER
This is a self-solder kit which is quick and simple to put together €“ even for an absolute beginner to electronics. This means as well as being a nifty little bit of kit to manage your Pi's power, it is also a great intro to electronics and soldering. As you can see from the pictures the input and output of the switch is fed by a standard USB connection. A USB cable is provided. Once soldered together, is essentially plug-and-play with your existing wall wart power supply unit.
The circuit is packed into a small profile so that it fits neatly into your workstation. The On/Off power switch is an essential piece of kit for all Raspberry Pi users!
Please Note: This board is known to work with RPi boards up to the Pi 3B. The newer boards after this have a higher current draw, this board would still work but a different/higher powered relay may be required.
