So it was probably 2009 when I got an arduino-based board as a gift, but as a child, could barely do anything other than upload the provided examples and make leds blink.
After years of drawer, I finally dug up the ATmega8 board. I'm still a beginner in Arduino-stuff, and given the giant leap tech took, I'm afraid my oldie needs an upgrade.

The question is very straight-forward:
Is it possible to upgrade - change the microcontroller - on the board? Is it worth it?
Are chips like this one suitable? https://www.adafruit.com/products/123?&main_page=product_info&cPath=17&products_id=123



Thanks in advance.

It might work, yeah. They've made other changes to the design of the board since those early boards, though - I don't know if they have the autoreset. If it's one of the ones where you needed to push reset to upload, it doesn't have autoreset, and modern bootloaders are designed for autoreset (the window to push the button is a fraction of a second instead of several seconds now, since autoreset pushes it at exactly the right moment, and everyone wants to minimize the time it sits in bootloader before starting sketch).

I would just get a new board.

The clones are insanely cheap now - $5-7 for uno clones, $2 each for pro mini clone - though if you buy only clones, you should adjust your karma by donating to Arduino.cc from the donate link you're offered from download page)

It doesn't NEED an upgrade.   It should continue to work fine with smaller sketches...

Yeah, it works fine with little codes. I will just leave it the way it is for now, and get another board whenever it's needed. Thanks!
