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.

Completely crazy. There are many flash devices with a controller on it, so a small computer, but that this thing has wifi is completely mind boggling.
Don’t forget that every recent Intel CPU contains an extra 486-based system on a chip running a stripped-down version of Minix (a predecessor of Linux), to implement the remote management engine.
May I present the ESP32?

Us hobbyists have been playing with it for years. Dual core too.
Well tbf it's just a microcontroller, it doesn't run Linux
Nope, it runs FreeRTOS, but it's still cool that I can build an internet-connected smart device in a package the size of your big toe nail using open software.
Yep, I go for it for almost every project I do, also because of the price. The amount of features you get for like 5 or 6 dollars is crazy.
MCUs can run Linux.
I don't use Espriff products so no idea if it is available for the ESP32.
