I just got my ardupilot, but noticed something wrong. Next to the 8 pin square chip I noticed a lop sided black component. I touched it and it fell off. After comparing to the image in the manual, it appears there was nothing there in the first place. Perhaps it came off from somewhere else? It is a tiny black rectangle, it says A6 on it. I will look over it some more, but what do you guys say? Any ideas?
