Do you happen to have schematics for the arducam cameras you sell? In particular, I am looking for OV9282 M12 and AR0234 M12 to find convenient points to solder in components for an external Fsync. I am trying to synchronize an array of cameras connected to multiple OAK-D PoE boards with an external IMU.

    Hi bob ,
    We just got back from Arducam; for OV9282 it's 200mA.
    Thanks, Erik

    Thank you for the response, that hadn't fully answered my questions, when extending it to larger arrays where power may come up at different times especially with an external source; the goal was mostly to avoid driving a signal into an unpowered camera. If schematic/layout isn't available , is there a spec for pin injection current?

    Hi @bob ,
    Unfortunately, we don't have schematics of these boards, but the FSYNC line is High Z input. Would that help?

    Many chips specify a current that you can safely reverse drive the internal ESD diodes without breaking them or causing latchup; the number helps choose appropriate series resistors for passive signal level translation. I will test; thank you for the help.
