Is there a keyboard case made of a model # A1584?

In addition, you can always use a separate external, wireless Bluetooth keyboard or wired keyboard with that iPad using a Lightning to USB adapter.

Plenty of separate, wireless Bluetooth keyboards available to use with that older iPad Pro.

Good Luck!

Very few, if any.

You have the same iPad Pro year and model as mine.

These iPads are almost 6-years old, now.

Look to Amazon. There are a few third party keyboard cases still available.

I am not a search engine.

Best of Luck to You!
