 SPI: SS, MOSI, MISO, SCK. Located on the SPI header support SPI
communication using the SPI library.
 LED: 13. There is a built-in LED driven by digital pin 13. When the pin is HIGH
value, the LED is on, when the pin is LOW, it's off.
 Analog Inputs. Six of the 20 general purpose I/O pins on the Zero provide analog
input. These are labeled A0 through A5, and each provide 10 bits of resolution (i.e.
1024 different values). They measure from ground to 3.3 volts
 TWI: SDA pin and SCL pin. Support TWI communication using the Wire library
