Product details
The LMP Large Font USB Keyboard KB-3421-BIG has been specifically designed for individuals with visual impairments. The size of the letters and numbers has been increased by up to 400%, making typing significantly easier for those with vision difficulties.
This robust USB keyboard features a 3-zone layout with 110 keys (ISO) and an anodized aluminum cover, complete with a numeric keypad. The characters are laser-engraved in large font, providing a pleasant feel under the fingertips. The keys have a traditional keystroke. Thanks to its high responsiveness and precision, even longer typing tasks can be comfortably managed. The elegant design allows the keyboard to seamlessly integrate into any desktop environment.
The two USB ports on each side of the keyboard enable the convenient operation of low-power USB peripherals, such as a USB mouse or USB flash drive.
The KB-3421-BIG can be connected to any Windows PC with a free USB-A port. It is available in two stylish color variants: Silver/White and Space Gray/Black. Any country layout can be accommodated upon request.
