So decent device, documentation is OK, and the LED wire colors can be whatever color they happen to use for whatever pin, so be aware and double check that you're connecting the right pin from the board to the LEDs or you'll blow them up or they won't work.
The real problem is that the power handling on this CANNOT handle 5v properly, despite the description saying it can. Apparently it was originally a 12-24v, they did some tests, and thought it'd handle 5v fine. Maybe they had to change parts or suppliers during the pandemic, but it can't handle 5v, keeps browning out. Solution from them is to put a wire shorting the diode next to the mic, essentially taking it out of the circuit, to avoid the voltage drop from it and it should handle 5v input just fine.
