+==== Camera Connector Pinout (15-Pin)
+
+This is the pinout of the 15-Pin Raspberry Pi CSI camera connector as used in flagship Raspberry Pi models before the Raspberry Pi 5. The connector is an Amphenol SFW15R-2STE1LF or compatible type.
+
+

+==== Camera Connector Pinout (22-Pin)
+
+This is the pinout of the Raspberry 22-Pin Pi CSI camera connector. The connector is an Amphenol F32Q-1A7H1-11022 or compatible type.
+
+NOTE: A Camera Module shall have reversed pinout to support Type A / Type 1 FFC cables. Pin 1 of the Raspberry Pi connects to Pin 22 of the Camera Module.
+Direction is specified from the perspective of the Raspberry Pi.
+SCL and SDA are pulled to 3.3V on the Raspberry Pi board.
+
+Function and direction of the GPIOs is Camera Module dependent. Most Camera Modules expect CAM_IO0 as Active-High Power Enable.
