3.1.6 Expansion Connectors (J8 to J12)
The M3A-HS37 is provided with through-holes for expansion connectors. The SH7137 I/O pins are connected to the
through-holes.
MIL-spec connectors can be connected to the through-holes (J8 to J12), allowing for connecting with expansion boards or
monitoring the SH7137 bus signals.
Figure 3.1.7 shows the pin assignments for expansionsion connectors.

Note： These pin assignments on the CPU board are defined on the assumption that
expansion connectors are mounted on the component side. If the expansion connectors are
mounted on the solder side, these pin assignments are not applicable.
