This Proto HAT is a HAT size universal prototyping board. You can have the total freedom to make your own project as you want, with prototyping boards that allow laying out the customised circuit to interact with the stickC port on top. The PIN's on top of the device are ported out for building more connections. For example, since the m5stickc has less hardware resources than m5stack, we can make that up with this HAT module, and if you want to add more buttons, you do it with the Proto Hat.
