I was going to make this exact clock with sections of RGB LED strip and was NOT looking forward to the process of wiring it all up. This is perfect. It is extremely easy to connect to it as if it were any LED strip. Within a couple minutes I had colors running just fine. A couple hours after that, I had the clock displaying the time with custom color effects cycling over it.
I'm still using an external ESP32 dev board, but definitely like the possibility of attaching the ESP32 directly to this in the future.
