Using this enclosure is easy. First, place your Arduino or Metro development board inside the enclosure. Then, use the four small screws provided to secure the board firmly. The bumpers should be attached to the bottom of the enclosure to give it a stable base. When you want to reset your board, just use the flexi - nub to press the reset button. Remember, this enclosure doesn't come with a development board, so make sure you have your own. To maintain it, simply wipe it with a soft, dry cloth to keep it clean. Avoid using harsh chemicals as they might damage the clear surface. Also, be gentle when attaching and detaching shields to prevent any damage to the enclosure or the board.
