Module Type Detection
The signals TYPE0#, TYPE1#, TYPE2# and TYPE10# indicate the pinout type of the module connected to the carrier board. These pins are either
open (NC), strapped to ground (GND) or connected to 12 V by the module as shown in the table below.

Note
If the conga-TEVAL3/COMe 3.1 detects an incompatible module pinout, an onboard logic prevents the board from powering up the whole
system by controlling the 'PS_ON#' signal of the ATX power supply.
