Differences between the Keymu and the later FunKey branded systems include the use of the Intel Edison's built-in eMMC memory for data storage rather than a microSD card, the lack of a speaker in the original prototype (though its open sourced specifications allowed for the inclusion of 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.
