Two board sizes:

There are three types of modules, each with different standards; Alpha, Beta and Omega.

Alpha Modules have integrated ESP32. They are the only modules with over the air connectivity. Each Alpha module has two RJ12 Beta ports and two RJ10 Omega ports.

Beta modules are not designed to workout an Alpha. Standard integration of a small speaker and a tuner.

Omega modules work in a chain using the WS2811 protocol across both data lines with one RJ10 in and one RJ10 out. Omega modules do not communicate back with the Alpha. Each WS2811 driver reports three values from 0-253 with as many sets as are needed to communicate along Omega modules. WS2811 light modules integrate seamlessly with other types of control.
