I didn’t see a unified thread discussing what accessories people have tried on their iPads since the iPadOS beta was released. Tonight I dug around in the garage and found a couple of things to try. I connected an old Logitech Lapdesk N550, and a Logitech K830 keyboard/trackpad combo unit. Both worked perfectly. The Lapdesk connected directed to the USB C port with an adapter, and the K830 connected via bluetooth. Once connected to the Lapdesk I was able to play audio from the Lapdesk as well as adjust the volume/mute. The K830 worked just like it should. I was able to use the built-in trackpad to move the cursor around and the keyboard to type. Shortcut keys worked as well. I recorded a short video for your viewing pleasure. What about you? Have you tried anything besides USB stick drives and external storage? Apple may have some other surprises waiting for us to find.
