CSI D (4-lanes CSI)
501951-2210 connector type
4 lanes MIPI CSI connectors
separate MCLK pin (pin 122 on Jetson)
I2C and PWND are 3V3 logic
pay attention to cable pins orientation (same / opposite side contacts). Cameras from different manufacturers can have different pin order, so wrong cable can cause short-circuit!
power to this connector is not protected so be aware of potential short-circuits on the connected devices.
