Cherry ML4400-USB Keyboard With Built-In Trackball

Cherry ML4400-USB is an ultra-flat, compact keyboard that includes a built-in 16 mm optical trackball, delivering typing and pointing capabilities in a single space-saving package. It uses Cherry’s ML technology with Gold Crosspoint contacts for reliable, crisp keystrokes in a low-profile G84-4400 chassis, and it follows a 75% compact layout with a full QWERTY keyset. The integrated trackball sits to the right of the alphanumeric area and is paired with two mouse buttons for left and right-click actions, enabling precise cursor control without a separate mouse—an ideal choice for data-entry work, point-of-sale terminals, kiosks, or other space-constrained setups. As a USB version of the ML4400 line, it connects directly to modern PCs for straightforward, plug-in operation, making it well suited to compact workstations or equipment panels where a single device handles both keyboard input and navigation.
