Camera connector

[VojislavM]

There is a difference between camera connectors on Raspberry Pi 1, 2 and 3 and Raspberry pi CM base board.

Raspberry Pi 3 camera connector:

Raspberry Pi CM base board camera connector:

Camera 1 interface is used as the primary camera interface

STEPS TO ATTACH A RASPBERRY PI CAMERA (TO CAM1)

• Attach the 0.5mm 22W FFC flexi (included with the adaptor board) to the CAM1 connector (flex contacts face down).
• Attach the camera adaptor board to the other end of the 0.5mm flex (flex contacts face down).
• Attach a Raspberry Pi Camera to the other, larger 15W 1mm FFC on the camera adaptor board (contacts on the Raspberry Pi Camera flex must face up).
• Attach CD1_SDA (J6 pin 37) to GPIO0 (J5 pin 1).
• Attach CD1_SCL (J6 pin 39) to GPIO1 (J5 pin 3).
• Attach CAM1_IO1 (J6 pin 41) to GPIO2 (J5 pin 5).
• Attach CAM1_IO0 (J6 pin 43) to GPIO3 (J5 pin 7).

Because we do not want to use camera adapter board, 15 pin connector will be used:

Camera connector:

It will be vertical SMD connector, because of the limited space inside of the Koruza unit. This way flax cable will easily connect to the board. Connector part number: 1-1734248-5 Available:

• digikey
• mouser

Differential trace length are matched with tolerance of 0.254mm and they have 100 Ohm differential impedance.

[VojislavM]

The SDA and SCL pins must be either GPIO0 and GPIO1 or GPIO28 and 29 and must be individual to each camera.

Camera 1 I2C and IO interface:

interface	GPIO	function
I2C0	GPIO0	SDA
I2C0	GPIO1	SCL
GPIO	GPIO4	CAM_GPIO
GPIO	GPIO5	CAM_CLK
