I have just made a project to control ORAC and also perform some device operation (network IP lookup / shutdown) using Pirate Audio hat.
The DAC on the hat can also be used for low latency audio output using Patchbox OS.
With the controller project, Pirate Audio can be a great HAT to play with ORAC headlessly.
I made a quick video to demonstrate it: Pirate Audio + Keybow = ORAC Fun
Hope you like it!
