+With a 10-bit ADC over an operating range of 0--5 V, the analog input pins have a resolution of 4.9 mV. Digital I/O pins can supply a maximum of 20 mA.
 It appears from the documentation that the serial pins (0 and 1) are internally connected to the USB interface [(docs_serial)]. In order to use both USB and another serial device, the ''SoftwareSerial'' library is necessary. In any case, serial operation is at TTL levels (//not// RS-232).
