The '''Keymu''' was a keychain emulator console created by Vincent and Michel of the FunKey Team in 2017. As with the later [[FunKey S]] system, the Keymu had a clamshell design based on the [[w:Game Boy Advance SP|GBA SP]], and was able to emulate games from the NES, SNES, and the entire [[w:Game Boy family|Game Boy system family]]. While it was never sold commercially, the part list, information, and diagrams needed to build the device were made available to the public so that others could create their own versions.

Inspired by the initial reveal of the [https://pocketsprite.com/ PocketSprite] in 2016, the duo worked on creating a similar keychain-sized emulator system that would have a clamshell design. Resembling the larger Game Boy Advance SP just as the PocketSprite had resembled the Game Boy Color, the Keymu was first shown off in a video released in June 2017. Due to positive reception to their device from viewers and several media outlets, the FunKey Team decided to improve the Keymu to turn it into a commercially viable product. Following the creation of the [[FunKey Zero|FunKey Zero]] prototype, a keychain system that resembled the original Game Boy Advance, the team created the [[FunKey S|FunKey S]], a slimmer and more powerful version of the original Keymu system.

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 contained the system's [[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. The Keymu also had a 1.5 inch (38.1 mm) 128 by 128 pixel OLED display that refreshed at a rate of 20 FPS. The Keymu was capable of emulating Game Boy, Game Boy Color, Game Boy Advance, NES, and SNES games, though unlike the FunKey S could not emulate the more demanding PS1. 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.
