== Concept ==
FACE Module ('''F'''unction '''A'''nd '''C'''onnectivity '''E'''xtension '''M'''odule) designed as additional/optional system board providing extended functionality and IO connectivity options. The interface between main system board and FACE module implemented with high speed, low pitch, and high pin count board-to-board connectors (B2B). Connectors’ pinout including signals mapping and description described later in this chapter.
== FACE Module Interface ==
=== Connectors Specs ===
Complete B2B receptacle and plug connector’s specifications shown in the tables below.

=== Connectors Pinout ===
The tables below provide complete pinout of extension connectors EXT1, EXT2 and signals mapping.
[[EXT1 connector HOST side pinout]]
Notes:
# Fit-PC3/3i features PCIe REF clock only on these signals
# Merged with PCI Express signals to Mini PCIe card on fit-PC3/3i
# Fit-PC3/3i support SATA3.0 with rates up to 6Gbps
[[EXT2 connector HOST side pinout]]
Notes:
# Merged with PCI Express signals to Mini PCIe card on fit-PC3/3i
# GPIOs on fit-PC3/3i
# Fit-PC3/3i design does not feature LVDS interface
== Layout ==
Host side extension connector’s footprints with respect to board geometry shown in the below layout captures. Host side extension connectors provide complete Host/FACE Module interface connectivity. FACE Module side may have either both or only one of the connectors, connecting only FACE Module relevant signals.
