The UltraBar X is a new input device for PCs that is currently crowdfunding on Kickstarter. The core set is priced at $270 plus shipping, and backers will face the usual financial risks of crowdfunding campaigns. Therefore, prospective buyers shouldn’t simply assume that the UltraBar X will be delivered as scheduled in April 2026 or that it will meet the expected quality standards.
Magnetic modules
The device contains individual magnetic modules that can easily be connected. There are several types of modules, as core module measures 199 x 50.4 x 59.6 mm and features a 7-inch display with a resolution of 280 x 1424 pixels. This module includes a USB Type-C port and supports wireless connections via Bluetooth and WiFi.
Environmental sensors included
The VivoCube is a much shorter module that comes with a 2-inch AMOLED touchscreen, while the so-called SenseCube sports a fairly extensive sensor array including mmWave for motion detection along with temperature, humidity and ambient light sensors.
Two other modules are basically input devices, namely the DotKey and the KnobKey. The former features mechanical switches, while the latter is a rotary dial. This accessory can also serve as a control hub for smart home setups and can control smart lighting, among other things. Last but not least, developers can use an SDK to customize these features.
