hello
i’ve purchased some hi-watt RGB LED’s, similar to these:
i want to make an addressable string of 50 of these big guys, preferably using 4-wire protocol (with clock wire).
How? I don’t mind if it’s a chip or a whole module. Also don’t mind if it uses some other protocol— does not have to be a standard.
I cannot find a discreet APA102 or SK9822— those chips seem only to be available with an on-board LED.
Could any of these work?
