What is it?

This electronics is solving the two biggest problems when using a Raspberry Pi.

• Adds the missing power button to the PI
• Provides save shutdown, even if the power plug is (unintentionally) removed
• Adds a robust USB-C connector to power every PI

Besides of those two features the biggest advantage

Using the SuperCap Pi the Raspberry Pi is able to remember its last state. That means:

• If the device was disconnected by removing the power cord while it was on, it will restart in "on-mode" after reconnecting the power cord
• If the device was off when removing the power cord it will remain off after reconnecting it and can be started using the power button
• If it was switched off by the power button it must be switched on by the power button
• If it was shut down by the shutdown command or via the user interface it will come up if the power button is pressed or the supply cord is (re-)connected

Applications

The inital idea was to build a powersupply for an arcade bartop that has a power button to switch the bartop on and off. It should prevent from corrupted SD card files if the power cord is unintentionally removed during playing. So it needs to have a UPS feature. Especially children are not willing follow a "boring" shutdown procedure. If the power cord is removed the device should savely shutdown itself. Initially it was designed for arcade machines but there are a lot of usecases where it fits like Raspi based:

• NAS
• Homeserver
• IoT server

I'm using it on all of my raspi computers at home because it is so convenient just to remove the power cord without the risk of corrupted SD-cards.

What makes it special?

There is no similar product available. It is a foolproof easy solution to power and operate a Raspberry Pi.

A stable powersupply is the key to successful operation of the board. I recommend to use the official raspberry pi USB-C power supply. With other (cheap) supplies you will most probably fail. This article gives great insight to this topic: About USB power supplys
