A second version of the Brydge 12.9 add-on keyboard for the largest iPad Pro will debut in July. Its all-aluminum casing will weigh less than its predecessor’s, it will use a newer version of Bluetooth, and the backlight will be brighter.
The Brydge line uses hinges that are also clamps to convert Apple’s tablet into a clamshell laptop. There are versions for all the various iPad sizes.
