Connectors, keepouts, and component max heights
Figure 5 illustrates the area of your baseboard where the SoM connects. The measurements are relative to the standoff
in the bottom-left corner, indicating the position for the three board-to-board (B2B) connectors (Hirose DF40C-100DP-
0.4V), two standoffs, and the following component regions:
A. Antenna keepout: Place no components and no copper in this region. This area of your baseboard is directly below
the SoM's Wi-Fi and Bluetooth antennas, so it must be kept clear of any metals to ensure strong radio signals.
B. Max height of baseboard components in this region is 2.8mm.
C. Max height of baseboard components in this region is 1.5mm.
Additionally, figure 5 indicates the location of pin 1 on your baseboard connectors. To see all the pin assignments, refer
to the pinout schematic.
