Brand: ELECOM Compatible Devices: Windows OS and macOS devices equipped with a USB port Connectivity Technology: USB-A Keyboard Description: Pantagraph Features: Slim Color: White This wired, slim mini-keyboard has a beautiful, one-piece design with a thinnest part of 6.5mm. The key type uses the "pantagraph method," the same as laptop keyboards, allowing for light key presses. A steel plate is built under the keycaps to provide a solid typing feel and stability. No special drivers are needed; simply connect the connector to your computer's USB port and it's ready to use. It has input modes optimized for both Windows OS and Macintosh OS. Used a few times. Selling because I switched to a wireless keyboard. No operational issues.
