There are many retro consoles on the market, but few are as small as the FunKey S. Based on the design of the Game Boy Advance SP, the FunKey S measures just 42.5 x 44.5 x 13.8 mm and has a 1.54-inch display. According to the manufacturer, the panel is IPS and operates natively at 240 x 240 pixels. The device is powered by an ARM Cortex-A7 processor that runs at 1.2 GHz, 64 MB of DDR2 RAM and has a microSD card slot for adding up to 128 GB of storage.
The FunKey S also has a 450 mAh battery and 10 mm mono speakers capable of outputting at up to 0.5 W. The device runs on a Linux-based operating system that the manufacturer calls FunKey OS and has a micro USB port for charging or transferring games.
The FunKey S has received over US$100,00 in funding on Kickstarter; eclipsing its campaign target of around US$34,000 by some margin. The device is available to order for €62 (~US$71) and has a delivery estimate of November 2020.
Retro Dodo has already received a prototype of the FunKey S. Retro Dodo stresses that the final models will differ from his prototype in several ways. He explains the various changes in the video below. The FunKey Project has published most of the files for the FunKey S on Hackaday.io if you are interested in reading them or building one yourself.
