This just popped up on my YT feed about using a usb C mouse plugged into the DJI RC 2, never knew this existed or seen it before so thought id post it,
From 6,36 worth watching if you didn’t know,
Checked on here first couldn’t find a mention of it also checked the internet found one DJI post/topic mentioned back in 2019 other than that it’s quite vague so I’m guessing that this may have been around for a while & maybe works with other DJI controllers 
Should work the same with a bluetooth one
This is the default behaviour for Android isn’t it?
I have no idea why you’d want to do it on a DJI RC though 
Even more to add to the VLOS argument.
They say useful for moving files around etc, what a load of bollocks
I’m not to sure why anyone would want to use a mouse on the rc controller either ‘ maybe sausage fingers ‘ 
Granted its not an apple pencil but whats to lose for a buck 29
Yep I have one of those for exactly that .
Most android devices i’ve messed with have mouse support. Usb a with an adaptor or direct c.
A bunch support keyboards too.
Time was you could use them to minimise whatever embedded app the device was running, use copy n paste functions etc.
