I bought 5 Arduino Uno R3 clones for $2.39 a piece off AliExpress and they were pretty good apart from shitty soldering on the headers.<p>They fill the &quot;can&#x27;t be bothered to read the 500 page long datasheet&quot; niche for me nicely. I remember having to get along with datasheets and simple programmers and writing PIC assembly back in the 1990s and I&#x27;m glad that time is gone.
