Component Height

To allow stacking of extension on the top side and on the bottom side of the board as well as using isolation bumpers it is required to follow the maximum component height recommendations.

All components on the top side should not exceed 15mm in height. Exceeding this limit will affect stacking of the board because different spacing between the boards might be required which can't be done with the spacers that are defined for Xplained Pro board stacking.
All components on the bottom side of the board should not exceed 2.8mm in height. Using taller components on the bottom side will prevent the use of the default isolation bumpers and might affect the required spacers for board stacking.
