Now the boards snap together: the Dotstar wing on top of the LSM303 wing, which is on top of the Feather M0.
That arrangement puts the accelerometer chip pretty much smack-dab in the middle of the entire thing. Which is exactly where it should be.
The white? I put a couple pieces of white label stickers (the ones I use to label the drawers in my parts cabinets) over the Dotstars as a slight diffusion layer to make them show better on camera.
