+
+  These displays use I2C to communicate, 2 pins are required to 
+  interface. There are multiple selectable I2C addresses. For backpacks
+  with 2 Address Select pins: 0x70, 0x71, 0x72 or 0x73. For backpacks
+  with 3 Address Select pins: 0x70 thru 0x77
+
+  Adafruit invests time and resources providing this open source code, 
+  please support Adafruit and open-source hardware by purchasing 
+  products from Adafruit!
