Given my order came to ufactory around 1st of April, that’s a good joke guys 
Sorry, at first we though it’s much safer to send the OpenMV without soldering, since the header might be hurt during the delivery. But now we are aware of it’s a big mistake. Would do the soldering and find other way to protect it in next batch. Thanks for your feedback, appreciate it!
Thanks, I will find a way through.
