SO-DIMM DDR4 Slots

CPUs used on the COMe-C55-CT6 board provide support to DDR4-2400 SO-DIMM memory modules. Only non-ECC modules are supported.
For use of this memories, on board there are two SO-DIMM DDR4 slots.
The socket placed on top side (CN1) is type LOTES p/n ADDR0208-P003A or equivalent, a right angle, low profile, reverse type socket, used for high speed
system memory applications.
The socket placed on bottom side (CN2) is type LOTES p/n ADDR0106-P003A or equivalent, and is a socket with performances similar to the other, only it is standard
type, not reverse. The two sockets together allow the insertion of up to 2 SO-DIMM modules, for support to dual channel memories.

Depending on the usage model of COMe-C55-CT6 module, for critical applications/environments on the module itself
it is available a 4-pin dedicated connector for an external +12V
The default FAN Connector is a 4-pin single line SMT connector, type MOLEX 53261-0471 or equivalent, with pinout
shown in the table on the left.
Mating connector: MOLEX 51021-0400 receptacle with MOLEX 50079-8000 female crimp terminals.
Alternatively, as a factory option, the COMe-C55-CT6 module can be equipped with a 3-pin single line SMT
connector, type MOLEX 53261-0371 or equivalent, with pinout shown in the table on the left.
Mating connector: MOLEX 51021-0300 receptacle with MOLEX 50079-8000 female crimp terminals.
Please be aware that the use of an external fan depends strongly on customer's application/installation.
Please refer to chapter 4.1 for considerations about thermal dissipation.
FAN_POWER: +12V_RUN derived power rail for FAN.
FAN_PWM: PWM output from the embedded microcontroller to the FAN (4-pin connector only).
