Notes on Designing the Printed Circuit Board for the User System
If the header board is connected to a user system, the heights of parts mounted around the
header board are restricted.
When designing the printed circuit board of the user system, consider the heights of components
within the range of the header board, as shown in Figure 1, so that the components mounted on the
user system do not interfere with the header board.
