Is it possible to use the raspberry pi 400 as an external keyboard on another PC or tablet using the USB-C (OTG) feature?

    Going by https://www.raspberrypi.org/forums/viewtopic.php?t=290760 the 400 does support OTG but it could be a cabling / power mess - I would rather use VNC to remote into the PC :-) Keyboard emulators (search HID keyboard Pi Zero) are all over the net for the Pi Zero - you would need to test it and handle keyboard entry / keyboard translation. Very expensive way to replace a £5 basic keyboard (unless you are doing key logging / injection attacks) and even then there are cheaper ways. –  Dec 05 '20 at 00:25
  • Should be the same procedure as for the Pi Zero: Pi Zero as HID: How to control PC Mouse from Pi Zero through USB? – Dmitry Grigoryev Dec 05 '20 at 12:26
  • @Andyroo thanks for the advice using VNC! Did not think of this alternative. Will try as well. I already have 10 keyboards laying around my desk and it was just a way to quickly connect an existing Pi 400 to another PI. – MisterGin Dec 06 '20 at 13:24
  • @MisterGin Would this help https://www.raspberrypi.org/blog/share-your-keyboard-and-mouse-between-computers-with-barrier/ I've not tried it but reads OK. Now if they had an iPad version I'd be happy... –  Dec 06 '20 at 16:56
