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.
schematic for ardu cam cameras?
Hi bob
Not sure if you have seen this, but I'm posting it anyway:
https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/sync_frames/#arducam-ffc-camera-syncing
Essentially, by using a 26-to-22 pin converter connector, you expose and drive the strobe signal to sync the arducam cameras externally.
Thanks,

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?
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.

Thank you!
