A tiny ARM and Linux-based single board computer from Next Thing Company (www.nextthing.co). Following in the footsteps of the Raspberry Pi, C.H.I.P. is touted as the world's first USD $9 computer. Unless a TV with an analog composite video input is the monitor, a VGA or HDMI adapter is required, plus keyboard and mouse, bumping up the $9 price to make it useful. Preinstalled with dozens of apps, ports include USB, Micro USB and a versatile 3.5 mm 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.
