1.c. Arduino Pin Usage

The Wixel shield connects to these pins on the Arduino:

  • Pin 0 (RX)
  • Pin 1 (TX)
  • Pin 13 (user LED)
  • 5V
  • GND

The shield uses the Arduino’s 5 V regulator to power the socketed Wixel. It is safe to use this shield in conjunction with other Arduino shields or electronics that also use these pins, though such electronics could potentially interfere with the operation of the Wixel shield (and vice versa). For details about the connections, see the Wixel shield for Arduino schematic in Section 1.d.
