Untoleranced dimensions
Note: 
1. Dimensions are in mm.
2. It is recommended to have a 5x5 grid of GND vias solidly connecting the exposed GND paddle of
the module to the ground plane on the inner/other layers of the host board. This will provide a good
ground and thermal transfer for the ATWINC3400-MR210CA module.
