Thank you!
I have ordered 10pcs and NONE of them are working! They came in a tiny plastic bag, not a proper packaging. This is so frustrating! I've been waiting for them few weeks, then I spent a day figuring out why the board is not working and soldering them and then unsoldering! After that I used one of my working chips and the board worked fine! ALL OF THE 10 CHIPS ARE GARBAGE! Such a waste of time!
