Available Peripherals

I think the peripherals are currently very limited. I am looking for a microcontroller shield that I can stack on the Au. My project currently has an RPi Zero W connected to a Br shield (with Br Female Headers) stacked on the Au board. When the prototyping is done, I will look for a more permanent solution.
