+SSD1306 OLED Display via I2C
+======
+
+Features
+--------
+
+Some features supported by the firmware:
+
+
+* I2C connection between the two halves is required as the OLED display will use this connection as well. Note this
+ requires pull-up resistors on the data and clock lines.
+* OLED display will connect from either side
+
+
+Wiring
