      @Aaky I'll leave it to others on the team to comment on the camera configuration questions. For the VOXL 2 mini J19 is similar to J19 on VOXL 2. But instead of having a "spare" i2c port it has the ESC UART port. But, yes, GPS and VOXL 2 IO will work the same as they do on VOXL 2.

        @Eric-Katzfey Thanks Eric for clarification. Can you please tag someone who can answer my query on camera configuration part? Also does this board have no B2B ports for expansion? I can see it has USB3.0 JST connector on board. So I guess my doodle labs connection can go directly over that USB JST?

          Hi @Aaky
          VOXL 2 Mini has insufficient power for a Doodle Labs radio over USB. You will need to make a special power splice cable from some other 5V source to power a doodle. But, the USB host port otherwise is the same.
          Please see this post: https://forum.modalai.com/topic/3589/connecting-voxl-2-mini-to-doodle-labs-helix?_=1721511946216

            @Vinny Thanks Vinny for prompt response. I also read somewhere regarding external CAP's to be used for high speed USB3.0 datarate. Do I need to do that for doodle labs modem? My doodle would be powered externally and not from VOXL2 Mini board for sure. I just need D+ and D- connections. Also suggest connection pinout since USB on VOXL2 Mini seems to be USB3.0 and Doodle labs USB is 2.0

              HI @Aaky
              As far as I know across a few generations of Doodle radios, they are USB2 only with D+/D-.
              Our cables we make for Doodle are only using USB2 lines as well, for example: https://docs.modalai.com/cable-datasheets/#mcbl-00085

                  Hi @Aaky

                  Yes three camera streams are OK (you can do 4 on voxl2 mini with the interposers we sell, e.g. M0135).

                  We don't have an SDK camera config that works out of the box but it's not too hard to build one up, see:
                  https://gitlab.com/voxl-public/voxl-sdk/services/voxl-camera-server/-/blob/master/misc_files/usr/share/modalai/voxl-camera-server/custom_camera_config.txt?ref_type=heads

                  For example, check out these:
                  https://docs.modalai.com/voxl2-mini-image-sensors/#quad-tracking

                  And this, https://docs.modalai.com/voxl2-mini-image-sensors/#camera-configuration-summary:

                    @modaltb Thanks for your inputs. So 1280x800 pixels streaming of two cameras (AR0144) over J6/J7 seems to be workable.

                      @Aaky agreed - not an issue with camera pipeline at all to do that.

                        @modaltb I also want to check the stock availability of new TOF sensor over here. Is this TOF camera available for shipping currently? I cant see that on website so wanted to check with you.
