From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have an old pentium laptop N3520 with 4GB DDR3. I removed everything and put it in a receiver box 1U size. It consumes so little energy that it can run 5-7 hours from its battery (I call it build in USV). Last time I measured 3-7w. Also passiv cooled , no noise. Another machine I use , is with a i7 4770 with 16GB for Proxmox, 7-20w , peak is much higher but rarely used , only on boot and vm startup.
Oh and the i2c etc stuff, I connected ESP32 and other microcontrollers over USB.
What is i2c?
A communication protocol used in microchips, small modules & embedded devices that uses 2 wires. Think something like USB, but dead simple.
