Camera Connectors J1000 (15), J1100 (16), J1200 (17), J1300 (18)
The Open-Q 845 µSOM Development Kit includes four camera interface connectors, J1000, J1100,
J1200, and J1300 allowing users to connect multiple camera adapters to the development kit. See
items 15 through 18 in Figure 1 for the carrier board locations of the camera connectors.
Intrinsyc offers compatible camera module accessories for the Open-Q 845 µSOM Development Kit

Exposed on each camera connector are the following interfaces:
•
One 4-lane MIPI CSI high speed camera interface
o
NOTE: The camera 4 connector J1300 includes only a 2-lane MIPI CSI interface.
•
Camera Control Interface (CCI) I2C bus for camera and actuator control
•
Additional GPIOs for general purposes available
•
Various power rails for powering the camera adapter
For details on the signal list provided on the camera connectors, see the development kit schematic
(R-3) and the camera adapter design guide technical note document (R-5).

Camera Flash Connectors J1001 (19) and J1201 (20)
In addition to the four camera connectors, the video capturing subsystem of the Open-Q 845 µSOM
Development Kit is equipped with two connectors for flash or torch devices (J1001 and J1201). The
PMI8998 power management IC has three flash channels, each with a maximum 1.5A rated
regulated current sink. However, the development kit exposes only two of the flash channels with a
0.25A current limit, due to the current limit of the µSOM connectors pins.
See items 19 and 20 in Figure 1 for the carrier board locations of the camera flash connectors. The
pinout of the connectors in shown in the table below. The typical interfacing to these camera flash
channels is shown in the figure below.
