I am so sorry that I failed in my last project due to the PCB problem.
I am really worried about the quality of products, which can damage my total project.
This time, I ordered from www.pcbgogo.com/b. It always in the first page of google. maybe it is reliable.
I received pcbs last day, it seems well made and high quality.
