Compact in size and portable.
The board’s size makes it an ideal choice for using this SBC on the go. The only feature we believe should have been included is a 3.7V interface for connecting a lithium battery, which would provide an uninterrupted backup power supply. Although the GPIO header is Raspberry Pi Zero W2 compatible and features 40 pins, it is not certain that every PSU expansion board will work with it.
If you want to avoid overspending on boards and experimenting, you can purchase an inexpensive LX-2BUPS board and solder a USB Type-C cable to it. This board supports a pair of 3.7V lithium batteries, which should provide a few hours of usage in the event of a power outage. Also, if you’re not using a hub for extra ports, you can simply connect the LX-2BUPS directly to the USB Type-C port.

The small form factor advantage: Tiny yet powerful
The Zero W3 board measures a compact 65 x 32 x 1.2 mm, making it an ideal single-board computer for outdoor use and easily portable in a small pocket. It can be powered through a standard 5V USB port, and the only additional accessory you may need is a mini USB hub.
