There is an entire website dedicated to this product with easy to follow instructions, code examples and various tools (search on Google: 2022 Hackaday Supercon 6 Badge Guide).
There is also a video that is full of amazing programs people have created (search on YouTube: Hackaday Supercon 2022: Badge Hacking Awards Ceremony).
I would list the links but eBay does not permit embedding links to any outside websites.
