This is the answer from ArmBoy1988 in the armbian forum:
The Logitech k400r is still available in Switzerland, it is a dektop keyboard with trackpad and his own 2.4G USB dongle.
biblioman09 showed on his YouTube channel a Orange Pi 5 with desktop usb keyboard and mouse which worked fine as well.
But these are desktop keyboards and mice, and I am looking for a wireless mini keyboard for the Orange Pi 5. But if the Logitech k400r works for you with it’s own 2.4G USB dongle, then
«Rii (Upgrade) i4 Mini Bluetooth Keyboard with 2.4G USB Dongle»
which has his own 2.4G USB Dongle eventually works as well.
The «Rii (Upgrade) i4 Mini Bluetooth Keyboard with 2.4G USB Dongle» supports both Bluetooth and 2.4G wireless with it’s own USB dongle, it is a dual keyboard, and it is part of the the Crosstalk Solutions Orange Pi 5 kit:
https://kit.co/crosstalk/orange-pi-5
Crosstalk Solutions says on his YouTube channel that is works, altough he does not show a proof of function.
Biblioman09 who tested a Wifi & Bluetooth module with the Orange Pi 5 Plus on his YouTube channel writes in the comments of his video, that Bluetooth keyboards and mice probably won’t work with the module he tested.
So if the The Logitech k400r with his own 2.4G USB dongle work with the Orange Pi 5, other wireless keyboard and mice with their own 2.4G USB dongle eventually work as well, but not Bluetooth keyboard and mice witout their own dongle. That is my hypothesis after I did a lot of resarch about this topic.
