8 Pin Female tall stackable Header Connector socket forArduino Shield.
A black plastic wire with a female DC power plug that can be used to connect devices that require 20A/220V. It has a length of 25cm and a thread diameter of 16mm.
If you need to connect a battery pack or wired power supply to a board that has a DC jack - this adapter will come in very handy! There is a 2.1mm DC plug on one end, and a screw terminal block on the other. The terminals are labeled with positive/negative assuming a positive-tip configuration (which is the most common)
