      Hi Asif,

      I'm not totally sure about the final use case (sensor driver and sensor implementations vary) but I can comment on the I2Cs on the hardware. In general you can have multiple I2C devices on the same bus (given they have ability to change slave addresses), so you may get away with multiples on a bus?

      I2C1 at J10 --> here normal use case is a magnetometer but yes you could use this, provided the driver looks for this port

      I2C2 at J14 -> here - this is 'spare' in our generic use case so should be OK

      Can you share PN of what you're trying to use? We don't have direct experience with ToF from Flight Core at this point to reference

      Nice work locating that setting, agreed it's not obvious to locate all of this info... Although this is VOXL2 documentation, the graphic here might be helpful to see the plumbing:

      I was able to use the v1.13.2-0.1.1 file with mission planner, it connected but said update was not required. I will keep an eye out for the v1.13.2-0.1.2 drop. Looking into my compass setup, its a new release from MRO, could be an issue there

      Hi @Filip-Slezak
      As far as I understand, FCv2 does indeed support CAN with no issues that I have heard of.

      I'm not able to help with SW issues, so please review these pages, and if you get stuck, please try to post a new Forum topic so our SW engineers can see it as a fresh case and respond accordingly.

      @modaltb I seem to be having the same issue of the flight core power cycling when battery is plugged in. therefore, esc calibration fails

      VinnyV

      @Will Have you considered purchasing another one? They are not expensive, and might be much more worth it than your time lost to fight a non-functional USB on the MCU.
      Food for thought...
      Sadly, I am not one of the SW experts in our team... just HW.

      Tag me anytime you have HW related questions!
      Thanks!

      @Alex-Kushleyev

      Yes, i believe that might be the case. There might be some other px4 firmware parameters that are causing it.

      Hi @daniel
      Please see responses below.

      @daniel said in FC2 schematic and board file:

      what is the purpose of STM32 UART7 through level shifters (74LVCH2T45)? both VCCA and VCCB are same 3.3V domain?

      Yes, an early proto-type design had that port at 5V, so we had the level shifters. We then changed it to 3.3V for our production version, so technically the level shifters would not be needed, but it will give you longer cable drive range because of it.

      J2 - where is VPP_STM connect to and what is the function?

      You can get this info from any STM device spec. We (a programmer device) use it the way STM specifies

      J5 - why there is no level shifter on UART5?

      It is not needed. See response above.

      J13 - Is that PM monitoring really need for FC? Can I just use a adc pin to monitor battery voltage through the divided resistors?

      That feature is your choice. The power monitoring will be MUCH more accurate since we use a 16-bit device as highlighted here https://docs.modalai.com/power-module-v3-datasheet/ , and it is capable of coulomb counting if the PX4 drivers that can do that. There are tons of research articles out there about pure voltage monitoring vs coulomb counting, so we leave it to you to decide what works best for you.

      RGB1 LEDs are controlled by GPO PE3/4/5, please confirm which pin for witch color.

      We go in order of the port pins noted as "RGB", so PE3 is RED, PE4 is GREEN, PE5 is BLUE. All are "Active LOW" to Illuminate the LEDs.

      Hope this helped!!

      To me, based on all the questions you've been asking these past weeks, it seems as if you are designing your own version of HW that you want to be compatible with our FCv2 firmware.
      If this is true, just let us know and we can try to assist you better. If you want a different form-factor for the board, that might be something we'd be interested in supporting if it helps you better. Just ask!
