While visually similar to the FunKey S, the Keymu used significantly different components compared to its "FunKey" branded successors. The Keymu was powered by the [[w:Intel Edison|Intel Edison]], an SD card-sized [[w:computer-on-module|computer-on-module]] board that combinedcontained the system's CPU[[w:Intel Atom|Intel Atom]] processor, 1 GB of RAM, and 4 GB of built-in [[w:MultiMediaCard#eMMC|eMMC]] storage, in addition to unused Wi-Fi and Bluetooth capabilities. Due to Edison's discontinuation soon after the reveal of the Keymu, however, future systems designed by the FunKey Team, including the FunKey S, would make use of the [[w:ARM Cortex-A7|ARM Cortex-A7]] microprocessor instead. Other differences between the Keymu and the later FunKey branded systems include the use of the Edison's built-in 4GB of [[w:MultiMediaCard#eMMC|eMMC]] memory for data storage rather than a microSD card, the lack of a functional speaker in the prototype unit (though it was possible to implement one), a lower maximum resolution of 128 by 128 pixels, smaller buttons, and a lower-capacity 220 mAh battery. Features only implemented in the later FunKey S and not in the Keymu or FunKey Zero include a magnetic "sleep-mode" mechanism, a protective glass layer above the display, a Menu button, 50 rather than 20 FPS, no screen tearing, and an improved hinge.
