1.8.5 SUMIT Connector
SUMIT is a connection protocol that integrates common high-and
low-speed serial and legacy expansion buses for dedicated use. A
compact, stackable, multiboard I/O expansion solution, the SUMIT
connector supports one x1 PCI Express lane, one x4 PCI Express
lane, and additional power, ground and control signals. Pin defini-
tions are as follows.
