Since it is based on the esp32, the main communication method is over WiFi. Setup, config, and control are very easy using the built-in web portal. Just point your phone to the url of the board and you’re good to go.

How To Get One

No production as of right now, but possibly in the future. It is 100% open source, so its possible to order PCBs, parts, and DIY your own board if you like. There is the potential of partnering with the right person to take care of the manufacturing side of things, or you could make and sell your own - its open source after all!
