While messing about with some designs to make at Ponoko, I wanted to get the dimensions for a couple of components in order to incorporate them into my designs, and realized that there wasn’t a particularly good collection for that. This is my attempt to start such a collection. The measurements aren’t displayed in the files because they are drawn with real-world measurements – if you open up inkscape the compass should be 1.5cm wide, a battery is 5.1 cm long and so on.
This is the Honeywell Compass module HMC6352, mounted by Sparkfun on a custom breakout board. It is listed for sale on the sparkfun website. (Note that these are the dimensions of the item I ordered, rather than the one listed – they seem to have shrunk the unit somewhat since listing the item)
I hope this is useful to someone some day!
