Where can I find the UART mapping for the cube orange+?

Hardware Pixhawk family

For example on the CUAV V5 Nano page there’s a handy reference chart:
https://ardupilot.org/copter/docs/common-cuav-v5nano-overview.html#uart-mapping

UART Mapping

  • SERIAL0 → USB MAVLINK
  • SERIAL1 → USART2 (Telem1)
  • SERIAL2 → USART3 (Telem2)
  • SERIAL3 → USART1 (GPS)
  • SERIAL4 → UART4 (UART4)
  • SERIAL5 → UART6 (TX pin is tied to RC pin)
  • SERIAL6 → UART7 (Debug)
  • SERIAL7 → USB SLCAN

But there doesn’t seem to be an equivalent chart on the Cube Orange+ page:
https://ardupilot.org/copter/docs/common-thecubeorange-overview.html#the-cube-connector-pin-assignments
I read the page at The Cube Module Overview | CubePilot and the only info I can find is that telem1 is serial1 and ADS-B is serial 5. And that UART2 is serial2, but no mention (that I can find) of what physical port that is. Either I’m reading the page wrong or some information is missing.

Also, according to the documentation it looks like the Here GPS uses the can2 port instead of the GPS port. Is this right?

If I’m reading this right it looks like GPS 1 & 2 are both available to be used as serial ports. Is this accurate? I need 4 ports for the project I’m planning and that would be really handy.

I may have just found it.

The cube UART maps are all the same, right?

Thank you!

Saving this so I can come back and find it later:

  • SERIAL0 → USB
  • SERIAL1 → UART2 (Telem1)
  • SERIAL2 → UART3 (Telem2)
  • SERIAL3 → UART4 (GPS)
  • SERIAL4 → UART8 (GPS2)
  • SERIAL5 → UART7 (spare, CONS)

SERIAL5 is dedicated to the Ping ADSB receiver if you have the ADSB carrier board, and you cant change that.

That is a good point. Thank you for reminding me. It would be silly of me to plan to use a serial port that’s using the thing that’s the whole point of buying the board in the first place for something else.

Speaking of, the hereGPS really does use the CAN port(s): Here 3 Manual - CubePilot Neat!

Thank you for this. I was strapped with the oscilloscope to Serial5 for 3h not understanding what I was doing wrong.
