The SBC-A80-eNUC board supports SO-DIMM DDR3L memories up to 1600MHz.
For use of these memories, on board there are two SO-DIMM DDR3L socket.
CN3 is type LOTES p/n AAA-DDR-109-K01 or equivalent, a right angle, high profile socket, h = 5.2mm.
CN4 is type LOTES p/n AAA-DDR-112-K01 or equivalent, a right angle, high profile socket, reverse type, h = 9.2mm.
Both of them are usually used for high speed system memory applications.
3.3.17 IR Receiver
The SBC-A80-eNUC board embeds an IR receiver, which allows using a remote control when the board is placed in an enclosure (like, i.e., on Set Top Boxes).
The Infrared Receiver is SMD Type, p/n TSOP75238TR, and works with 38kHz carrier frequency.
The IR port is managed by the embedded microcontroller.
