AT Tiny is a microcontroller.
You may be thinking of Arduino, which is another family of small cheap embedded
computers with a complete ecosystem. Unlike Pi and BeagleBone, Arduino uses a
small RTOS. The original ones were AVR based; later ones use ARM. Either way,
a complete system might cost 10-20 dollars. Check our "Arduino Nano" or
"Adafruit Trinket". I used the latter in my LK201 keyboard emulators.
Yet another one is Raspberry Pico, which in spite of the name is nothing like a
Pi and doesn't run Linux. It's conceptually like Arduino but both more
powerful and less expensive. I built a DDCMP sync line controller out of one
of those. Once again, not Linux but rather an RTOS.
Neither of these come standard with Ethernet, though I've seen option cards.
In the case of Pico, it seems possible to do 10 Mb/s Ethernet in software using
its PIO controller, though I haven't made the atttempt.
