Background
HopperHawk started as a project for myself, and I never intended on releasing it out into the world. It’s also the first project that involved building custom PCBs, so when I started out I went as simple as possible to reduce complexity and cost. The project gained some traction and more people were interested in it than I expected. After several iterations and hardware changes, it is finally in a place where I can share it with others!
