This pair of 4 pin Female/Male header strips is very useful for Arduino board extensions. They can be used with any Arduino shield because of their height.
These are assorted headers that are great for many projects. They are spaced with the standard 2.54mm or 0.1". (5) 2, 3, and 4 pin headers. (3) 5 pin headers, and (2) 10 pin headers.
Use these roll pins to fix sprockets to a shaft and keep them locked in place.
This is our prebuilt HD2-S robot modified with a 5 axis robotic manipulator arm. This robot is loaded with all the options including a programmable Arduino. Ready to ship.
