The Core features three serial ports. The first one is a CDC (Communications Device Class) available over the USB port. When configured, it will show up as a virtual COM port on the computer. (usage: Serial.begin(9600);)

The third one is a hardware USART available via the D1(Tx) and D0(Rx) pins on the Core. (usage: <code>Serial2.begin(9600);</code>)

Configuration and use of all of these serial ports is described in the serial functions.

Configuration and use of all of these serial ports is described in the [http://docs.spark.io/firmware/#communication-serial serial functions] (''Spark, anglais'').

NOTE: Please take into account that the voltage levels on these pins runs at 0V to 3.3V and should not be connected directly to a computer's RS232 serial port which operates at +/- 12V and can damage the Core.
