Title: What are these led strips?
Post by: atlas2003 on Sep 23, 2017, 08:05 pm
Hi everybody.

Few years ago, I bought this led strip directly from a china store. I don't remember which one and I don't remember the ref of this item :( So i don't know how to drive it.
As you see on the pic, I can't read the ref number on the IC because of the semi-translucent plastic...

Maybe one of you know what it is?
