Single-board computers need a reliable power source to function. 

Depending on the particular board, you might require a micro USB cable, a USB-C cable, or a special power supply converter.

MicroSD cards or eMMC modules are frequently used by single-board computers.

 You could need different storage devices like microSD cards or USB flash drives if you need more space.

A casing or enclosure can shield your single-board computer from physical harm, static electricity, and dust.

 You can utilise wired or wireless peripherals depending on your preferences and the board's compatibility.
