    FFC connector pinout?

    in Interceptor Carrier Board

    Over on https://www.axzez.com/forum/interceptor-carrier-board/40-pin-ffc-gpio (topic is closed or I'd reply there), I see that the FFC connectors expose I2C and some GPIO pins. I'd be interested in using them for some uses other than network interfaces. Could someone (@Bill Nagel perhaps?) post the pinout? Thank you!

    This is the FFC connector we use:

    Pins 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40 are ground

    Pins 8, 9, 10 are 3.3V

    Pin 11 is ID_SD

    Pin 12 is ID_SC

    Pin 13 is GND on J9 and 3.3V on J10

    Pin 14 is GPIO4 on J9 and GPIO6 on J10

    Pin 15 is GPIO5 or J9 and GPIO7 on J10

    Pins 1-7 on J9 and J10 are all tied together.


    ID_SD and ID_SC have internal pullups on the CM4.

    Pins 14 and 15 have 1.8K pullups on the interceptor.


    Our PoE board uses an AW9523 to add GPIO to control LEDs. We connected it on Pin 11/12 and use pin 13 to set the address pin of the AW9523 so that both AW9523s can be on the same i2c bus. Pins 14/15 should also be suitable for i2c.
