Signal Pin # Description
TYPE10# A97 Dual use pin. Indicates to the carrier board that a Type 10 module is installed. Indicates to the carrier that a Rev.
1.0/2.0 module is installed.
TYPE10#
NC
PD
12V
This pin is reclaimed from VCC_12V pool. In R1.0 modules this pin will connect to other VCC_12V pins. In R2.0 this
pin is defined as a no-connect for Types 1-6. A carrier can detect a R1.0 module by the presence of 12V on this pin.
R2.0 module Types 1-6 will no-connect this pin. Type 10 modules shall pull this pin to ground through a 4.7k resistor.

Pinout R2.0
Pinout Type 10 pull down to ground with 4.7k resistor
Pinout R1.0
Description
Primary power input: +12V nominal. All available VCC_12V pins on the
connector(s) shall be used.
Standby power input: +5.0V nominal. If VCC5_SBY is used, all available
VCC_5V_SBY pins on the connector(s) shall be used. Only used for standby and
suspend functions. May be left unconnected if these functions are not used in
the system design.
Real-time clock circuit-power input. Nominally +3.0V.
Ground - DC power and signal and AC signal return path.
All available GND connector pins shall be used and tied to Carrier Board GND
plane.
