IR receiver - front side
I ordered these boards at SeeedStudio about 3 weeks ago. The usual shipping time to me. And that is called air-mail. HAH. I'd really like to know how much of it is caused by delayed customs processing. Instead of creating more jobs for inspectors they make us wait... as if I were ordering illegal stuff like 20mW laser pointers ;-)
