Recommended Footprint for the Application
Figure 26 shows the recommended footprint for the application board (dimensions are in
mm).
To facilitate replacing the LE910Cx module if necessary, it is suggested to design the
application board with a 1.5 mm placement inhibit area around the module.
It is also suggested, as a common rule for an SMT component, to avoid having a
mechanical part of the application board in direct contact with the module.
NOTE:
In the customer application, the region marked as INHIBIT WIRING in Figure
26 must be clear of signal wiring or ground polygons.
