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);)

== Bus SPI ==
The Serial Peripheral Interface is available on pins:
* A2: SS (Slave Select)
* A3: SCK (Serial Clock)
* A4: MISO (Master In Slave Out)
* A5: MOSI (Master Out Slave In)
{{SPARKImage|Spark.IO-Brochage-SPI.jpg|480px}}
NOTE: All of these pins run at 3.3V logic levels.
== Bus I2C ==
I2C communication pins are multiplexed with the standard GPIO pins D0 and D1.
* D0: SDA (Serial Data Line)
* D1: SCL (Serial Clock)
{{SPARKImage|Spark.IO-Brochage-I2C.jpg|480px}}
Both of these pins run at 3.3V logic level but are tolerant to 5V inputs.
