Add your favorite Adafruit development board to your next brick-build with the Adafruit Feather Mount for LEGO-Compatible Brick Systems. This does exactly what it says on the tin: if you have one of our 'standard sized' 2"x0.9" Feather or Featherwing boards, you will be able to snap-attach it nice and flat to any LEGO-compatible brick plates. This lets you skip the hot glue, epoxy, tape for a lovely secure build.
