I feel like the Atmega range asks an awful lot for what you get in 2024.
Of course, that could be because I designed a project around the Teensy++ which was always pricey and promptly disappeared from stock. I redesigned to use a CH32V305 breakout instead- 1/3 the price and probably way more performance which my terrible code is just busy-waiting into the ether.
I like WCH’s product line in general; it’s full of zany stuff.
