    I have a tbs crossfire receiver. I want to know can I connect this with the j3 UART-usb3.0 expansion board as it has support for UART7.
    thanks in advance.

      @voxl-phoenix What PX4 driver are you intending to use with it? And why don't you want to attach it to the "normal" RC UART on J19?

        @Eric-Katzfey My apologies I'm really new to drones. I don't know which firmware that I should use for the connector. I already have a TBS crossfire RC with me which I used with voxl-flight. so I thought it would be easy for me to use it with the UART expansion port.

        can you please suggest me what will be the best approach. which connector can I use to connect this to J19 port.
        thanks.

          @voxl-phoenix VOXL 2 is really not a great place to start if you are new to drones. And the best way to start with a VOXL 2 is with one of our pre-built drones like the Starling 2 (https://www.modalai.com/products/starling-2), not with a bare board. The standard place to connect RC for PX4 is J19.

            @Eric-Katzfey Thank you for the suggestion. but I have some constraints to use a prebuilt drone I have to build a custom one. so as you suggested I can use just a 12-pin adapter. I'm not intending to use any GPS or GNSS module.
            do you think that works?

            thank you.

              @voxl-phoenix J19 has pins for 2 UARTs. We put GNSS on one and RC on the other. So if you are able to hook up everything correctly, configure the TBS crossfire receiver correctly, and configure PX4 correctly then it should work.
