Raspberry Pi Zero is a reduced version of Raspberry Pi, but it does not mean that it is not as powerful. The new version of Raspberry Pi has created various projects and accessories that we normally use and that with this board we have the same enhanced accessory.
A good example of this we have in the USB key that NODE has created with a Raspberry Pi Zero, a USB key that has all the power of a USB key but powered by a Raspberry Pi Zero board which adds the possibility of having a mini computer running.
In order to build this accessory, we just need a Raspberry Pi Zero board, an accessory called MalDuino and a printed casing that protects and stores the USB port. Once we have this, we only have to connect the MalDuino accessory to the Pi Zero board, to be more exact, to the microusb ports of the board, to not only pass power to the device but also to provide power to the Pi Zero board. .
Raspberry Pi Zero can upgrade any device, even a simple USB
If instead of using the Pi Zero, we use the Pi Zero W, tWe have a StickPc that we can connect to remotely. The storage of said USB can not only be modifiable thanks to the slot for microsd cards but we can also use virtual storage thanks to the Pi Zero W being connected to cloud hard drives.
If you want to build such an accessory, you just have to go to the NODE website where there is an English guide and a video containing a visual assembly guide. Also in this link you can get the Malduino accessory, an accessory that contains a USB port connected to an Arduino-based controller which can be connected to other devices.
