I got caught with this piece of junk thinking it was UNO compatible. The xtal is marked at 16 mhz however as others have said the Blink sketch runs quarter speed. Alo the lcd key pad shield doesn't work so I'm glad it only cost around $3. I may investigate or put it down to experience.

I was doomed with some of these clones... the ADC is 12bit indeed, and you can revert to 10bit with calling

analogReadResolution(10)

from setup. But the ACD is very noisy and returns very imprecise values.


Has anyone here managed to get i2c or SPI to work with this arduino ? With i2c it just hangs during setup...
