Hi
The number of bits and the performance of the ADC’s on the Arduino’s is pretty
underwhelming compared to the stuff on other similarly priced MCU’s. If you are
doing a design where the ADC matters, a PIC or just about anything from TI or
Freescale will do a better job.
That's what actually drove me to the teensy3.. 16 bit ADC (no, you
probably can't get that kind of accuracy, but 13-14 bits, yes) with
differential inputs. It's based on a Freescale Kinetix ARM MCU
A lot more memory than the Arduinos, too.
My only complaint with the micro-b USB is that it's awfully easy to rip
that connector right off the board, and then it's "buy a new board"
time, because soldering wires on is almost impossible: the pads and
traces most likely went with the connector.
If I do a board layout for these things, I'd use a standard 0.1" center
header and a USB to header adapter or something, like they do on PC mobos.
