A tiny ARM and Linux-based single board computer from Next Thing Company. Designed for hobbyists and following in the footsteps of Raspberry Pi, C.H.I.P. was touted as the world's first USD $9 computer. If a monitor does not have a VGA or HDMI input, an adapter is required. In addition, a keyboard and mouse are necessary, all of which bump up the $9 price to make it useful. Preinstalled with dozens of apps, ports include USB, Micro USB and a versatile 3.5mm TRRS port for audio and 720p video. Featured in a 2015 Kickstarter campaign that drew overwhelming response, the C.H.I.P. began to ship in 2016. Raspberry Pi was much more popular, and two years later, the company went out of business.
