We know the CHIP computer, we connected to WiFi, we used UART, we tried WiFi speed connection and USB flashdisc, we measured power consumption during the boot and after boot and we blinked with LED. Today, we use USB webcam. At first I wrote that's very easy and you can you use it for a Raspberry Pi Zero, a Raspberry Pi, a BeagleBone, an Odroid and another SBC's, where you use a debian or fork of the debian (an ubuntu, a minibian etc.). It's very simple.
