Question about the Airbot Mini Carrier Board

Hello everyone. I have a quick couple of questions about the Airbot Mini Carrier Board v1.4 As I understand the documentation, I MUST select an RC Input Signal method by making the appropriate solder bridge? If I am using a higher powered radio such as the HereLink Air Unit, or the MK15 Air Unit, I do not NEED to make a solder bridge for the RC Power? Thanks!

These are signal and power selection. (sbus and 5v as default)
Herelink airunit and MK15 Air Unit are both sbus.(signal will be the same)
Need connect to external power for these high power unit,so no need to do any thing for this part as well.
Yes,do not need to make any solder bridge.
