MIPI-CSI2 Connectors
SBC-C31 with RK3399 SoC includes an Image Processing Subsystem,
that can be used for video applications, like video-preview, video recording
and frame grabbing. For this reason, the SBC-C31 can offer up to two MIPI
CSI serial camera interfaces, both supporting up to four differential data
lanes.
It is possible to access to the video input ports CN16 and CN17 through an FFC/FPC connector, type
HIROSE p/n FH12-18S-0.5SH(55) which is able to accept 18 poles 0.5mm pitch FFC cables.
