| ==== 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. | ||||||
|
|
||||||
| 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. | ||||||

There was a problem hiding this comment. 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). There was a problem hiding this comment. Also, according to the style guide, the "2" in "I2C" shouldn't be superscript. There was a problem hiding this comment. 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. | ||||||

There was a problem hiding this comment. Do we need the word "number" ("No.") here? Could we just have "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. | ||||||
