    Hello,

    I understand that the VOXL2 does not have support for UAVCAN. However, I was curious what a workaround might look like. Would it be adding a ESP232 board to translate from UAVCAN to i2c and writing a driver for that? Would it be creating a USB device that takes UAVCAN messages and shoots them off to the PX4 instance running on the DSP?

    Was curious if anyone had thoughts on this as there are a lot of UAV/DroneCAN peripherals

      @Eric-Katzfey

      For the near term, we could integrate a teensy board (https://www.pjrc.com/store/teensy41.html) that supports can bus hardware, gets information from the CAN device, and then relays that to the VOXL2 over UART using the ModalAI IO software.

      For the longer term, Modal is hoping to support CAN on their VOXL2 IO board, but that is minimum 6 months out

        I also just realized this was also kind of answered here: https://forum.modalai.com/topic/2735/enabling-can-driver-on-voxl2?_=1698720944161

            @wilkinsaf Nope, haven't. There seems to be a variety of devices out there that could be suitable but we haven't had a chance to evaluate any of them. If you are only trying to talk to a single CAN device it seems like there should be a simple UART to CAN adapter board available that would do the appropriate conversion. But, again, we haven't seen or tried anything like that. We would definitely be eager to hear if someone has successfully implemented something like that.

                    @wilkinsaf Haven't seen anymore conversation on this topic, and find ourselves facing similar requirements. Wondering if you've made any progress evaluating options or integrating/testing anything?

                      @Denver-Hopkins We had other projects come up. But this is starting to creep to the top of our list. If you would like to fast track it, feel free to email me at andrew.wilkins@ascendengineer.com
