Qx7 unused connectors

Post by maxfpv » Fri Oct 06, 2017 10:57 am

Inside the taranis qx7 there are two connections labelled p400 and P401 that are unused, does anybody know why they are there or if they could be used for something like extra switches. I have attached a picture.

They are 2 extra switch inputs but which do not currently have software support in OpenTX.

I have added support for these in recent test versions of ersky9x.

That’s good to know Mike.
Do you possibly have a pinout or them?
How would one use them, as a 2 pos sw closure, or 3 pos? Maybe with a pot?
Thanks

One pin is ground and the other connects to the processor that has an internal pull up resistor. Use them for additional, 2-pos switches, where the switch simply either leaves the two pins unconnected, or shorts them together. They are digital inputs, so no pot possible.
Configuration is done in the Hardware menu where you have two possible extra switches, PB1 and PB2. Set these to use either EXT1 or EXT2 depending on which connector they use.
