    @Ed-Sutter Hi Ed, I just now see you made two posts, so that other link along with this link is the bulk of what we have for showing the system level connections in a Voxl Flight Deck: https://docs.modalai.com/flight-deck-datasheet/#2d3d-drawings The Flight-deck exposes the ModalAI "Legacy" B2B (board to board) 60-pin connector which supports our modems, Microhard, and "debug" boards. All of those products support additional USB downstream ports so you can keep your primary USB to Voxl clear and open for ADB/Updates. https://www.modalai.com/products/voxl-debug-board-v2 https://www.modalai.com/products/voxl-lte?variant=32449203601459 https://www.modalai.com/products/voxl-microhard-modem-usb-hub Our schematics are not open hardware, but we do share a lot more than most. So if you need more info, please let me know. Thanks!

    Hi, The same software stack runs on both VOXL and VOXL2, in which we have a voxl-mapper project for mapping/planning (though this is still firmly in beta and under active development by our team). The VOXL is capable of performing the mapping on its own, but the software stack is heavy and will take up a larger portion of the processing power on the weaker board. The VOXL2 is able to support more sensors and more processing, but with the obvious tradeoff of the higher price point. It'll be dependent on your use case which one you will want to use.

    Hi, We've never tested QVIO on the hires cam, it's been extensively tuned for the fisheye tracking camera and benefits heavily from having a wide field of view. I suspect that this is where you issue originates. You are more than welcome to try this but you'll need to make sure that you've calibrated the hires camera and have defined accurate extrinsics between the camera and the IMU, but even with these done well it's likely to behave worse than the wide FOV tracking camera.

    We have the full toolchain and setup dockerized here: https://gitlab.com/voxl-public/rb5-flight/rb5-flight-px4-build-docker Following that setup, you will install the Hexagon SDK which provides more info on the lower level stuff. But, the PX4 code as shown above is what runs on the DSP.

    @Yusuf-Saib If you do ifconfig on your host machine you will get the IP address of that, not of the VOXL. So in your output it looks like you are trying to ssh to yourself.

    VOXL comes in the VOXL-Flight configuration, which basically mates up an STM32 based flight controller (the Flight Core v1) with VOXL, then there's an internal UART connecting the two, and you can control the Flight Controller with 8-PWM outputs. VOXL2 does support (currently in beta) the VOXL2 IO board which provides PWM outputs, and we've used it on a hex. See here for info on that use case. Again, this is in beta (not directly in the VOXL SDK at this point but in the dev channel). Depending on your size constraints, VOXL2 also can be used like VOXL-Flight, where you can use an external flight controller (like Flight Core) externally, which has 8-ch PWM. See here for info on that use case. (Why not native PWM? The VOXL/VOXL2 platforms are Snapdragon 820/865 based, which are primarily used in cell phones.... The PWM feature is not needed in cell phones, so these type of SoCs don't generally have native PWM...)
