Many Adafruit Feather boards are capable of simulating USB HID devices, like keyboards and mice. So why not have a shield that makes it easy to add a small macro keyboard to your computer? Or, you know, a set or really nice buttons with color LEDs to your project.
A²B Feather Wing
By David Knochenhauer:
For my daily work at a big car manufacturer in germany there was the need to have a simple solution testing the A2B Audio Bus. The Feather ecosystem is a perfect match since we can combine several architectures with various programming styles.
A2B nodes can be either master or slave and they can be bus powered (slave nodes only) or local powered.
The first prototype will be a local powered node, which can be either master or slave. Next will be a phantom powered slave node, so you can provide power over the A2B bus.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
