==== Camera Connector Pinout (15-Pin)

This is the pinout of the 15-pin Camera Serial Interface (CSI) connector used on flagship Raspberry Pi models prior to the Raspberry Pi 5.
The connector type is an Amphenol SFW15R-2STE1LF or a compatible equivalent.

The connector is compatible with Amphenol SFW15R-2STE1LF.


Signal direction is specified from the perspective of the Raspberry Pi.
The I^2^C lines (SCL and SDA) are pulled up to 3.3V on the Raspberry Pi board.

Don't know if this is elsewhere in the data sheet, but I believe (based on the International System of Units) that there should be a space between "3.3" and "V", so "3.3 V" (rather than 3.3V).

Also, according to the style guide, the "2" in "I2C" shouldn't be superscript.

In this case it should: see e.g. https://en.wikipedia.org/wiki/I%C2%B2C


The function and direction of the GPIO lines depend on the specific Camera Module in use. Typically, CAM_IO0 is used as an active-high power enable.

Do we need the word "number" ("No.") here? Could we just have "Pin"?

==== Camera Connector Pinout (22-Pin)

This is the pinout of the 22-pin Camera Serial Interface (CSI) connector used on the Raspberry Pi Zero series, the Compute Module IO boards, and flagship models since the Raspberry Pi 5.
The connector type is an Amphenol F32Q-1A7H1-11022 or a compatible equivalent.
