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
