The Makey Max Backpack is just that... it's ALL of the inputs that are on the back of the board broken out to easy to clip to "gator bites". The Max is inspired by the work of Jason Webb and gives you total access to as many inputs as possible and can be reconfigured through our remap tool for even more potential and versatility. If you are looking to take your Makey Makey projects to the max, this backpack is for you!
