can you use a smart keyboard with ipad pro 2nd generation?

Apppe no longer sell the smart keyboard cover for the older 2015-2017, 12.9 inch screen iPad Pro models.

You can check online places, like Amazon

OR

You can use other third party Bluetooth keyboard covers designed for these older iPad Pro models.

Again, look to Amazon.

Also, look at companies,,like Logitech, Zagg, Brydge keyboards for other Bluetooth alternatives.

Best of Luck to You!
