My DuinoKit Has Arrived!
This is a great kit for the classroom! All devices come pre-installed on a quality circuit board mounted in a beautiful hinged metal carrying case that has a removable cover. Not only does this kit provide a large number of actuators and sensors, but includes discrete devices, such as capacitors, resistors, diodes, and transistors that are all mounted on the printed circuit board.
