Hi, years ago I got a RGB led with RGB- pins on the PCB. Now I need another strip but cant find one with same pin out. There are still available?

Your search term is ‘Keyes RGB LED Module for Arduino’ or ‘KY-009’.

Hi @enrique292754

Welcome to the forum!

Those “dumb” style RGB strips are a bit harder to find now days as addressable strips have become more user friendly and popular, we currently don’t stock any strips that would match the specs that you mentioned by you may have luck with 5050 RGB strip as a search term.
