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

The wiring for i2c:

i2c wiring

The pull-up resistors may be placed on either half. It is also possible to use 4 resistors and have the pull-ups in both halves, but this is unnecessary in simple use cases.
