I was doomed with some of these clones... the ADC is 12bit indeed, and you can revert to 10bit with callinganalogReadResolution(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...
There are different clones...
The most boards from WAVCAT use a real ultra low cost clone and you can only use it with the WAVCAT board components inside the Arduino. The code is not compatible and the chip is also not compatible, but they write ATMega 328, even if it isn't an ATMega. The most people reports that it is so bad, that you can't use the most functionality of the real ATMega and it can't reach 4MHz.
And then, there is the LGT8F328P. This seems to be a good clone and is not from WAVCAT (they just use it). It has a 12bit ADC, 32MHz, a unique ID and also a DAC pin. I never had one.
