USB cable with type A connector on one side and type B on the other with a length of 40cm.
It is normally used to connect the
Arduino UNO or the
Ardunio MEGA .
As it is the same type of cable that is used to connect printers, it is very likely that you already have a few around the house so, go look at the cable box and if you already have one, that you save and the planet will be grateful also.
