Description
The Type pins indicate the COM Express
pin-out type of the Module. To indicate the
Module's pin-out type, the pins are either not
connected or strapped to ground on the
Module.
The Carrier Board has to implement additional
logic, which prevents the system to switch
power on, if a Module with an incompatible
pin-out type is detected.
Indicates to the Carrier Board that a Type 10
Module is installed. Indicates to the Carrier
Board, that a Rev 2/Rev 3 Module is installed.
