The two IO connectors J14 and J15 are standard 100 mil pin headers mounted on the back (non-component
side) of the 12311-MRB.The primary header J15 is 20-pin and the secondary header J14 is 18-pin, and
they are mounted physically in such a manner as to prevent reverse insertion of the 12311-MRB into a
motherboard receptacle (see
motherboard is plugged into these connectors, they allow access to MC12311 MCU GPIO.

V_BRD is the connector supply voltage.
— Depending on power supply configuration, this voltage may supply the 12311-MRB from the
— Peripherals IO to the MC12311 and the MC12311 supply should use this same voltage
Some of the GPIO are shared with onboard devices. Check for the 12311-MRB schematic and
