Microsoft Surface Adaptive Hub – J71-00004
 
The Microsoft Adaptive Hub is a wireless accessibility device that lets you replace or enhance a traditional keyboard by building fully custom inputs. This central assistive technology hub connects to up to three devices via Bluetooth or USB-C®, and pairs wirelessly with up to four Microsoft Adaptive Buttons (sold separately). It also supports your existing assistive tech — including third-party switches and digital buttons — through five 3.5 mm ports, making it a versatile disability accessibility accessory for PC and mobile setups.
 
Build custom inputs without a keyboard
Pair the adaptive hub with up to four wireless buttons or standard wired switches to design a personalized control setup that puts accessibility and ease-of-use first. 
 
Boost productivity beyond a standard keyboard
Combine the hub and wireless adaptive buttons to simplify multi-step tasks on any Windows PC or phone — ideal for users seeking custom macro shortcuts and streamlined navigation. 
 
Compatible with your current assistive technology
Five 3.5 mm ports let the hub integrate with third-party switches and digital buttons you already use, extending your existing accessible tech ecosystem. 
 
Personalize with interchangeable buttons and toppers
Choose a d-pad, digital joystick, or dual-button configuration, and further customize with 3D-printed button toppers available through Shapeways.
 
Flexible, expandable hardware setup
The wireless, expandable design supports up to four Microsoft Adaptive Buttons plus third-party accessories and switches — a scalable solution for adaptive computer accessories.
 
Accessible by design
