1 Introduction
- The BakeBit - OLED is a monochromatic OLED module. The OLED is 0.96" and its resoltuion is 128 x 64. Its interface is I2C.
- Users can set the I2C's address to either 0X3C or 0X3D and place two OLED modules on one I2C bus.
2 Hardware Spec
- Standard 2.0mm pitch 4-Pin BakeBit I2C Interface
- Resolution: 128 x 64
- Color: blue
- I2C's address configurable
- PCB dimension(mm): 24 x 42
- Pin Description:
| Pin | Description |
| GND | Ground |
| 5V | 5V Supply Voltage |
| SDA | I2C-SDA |
| SCL | I2C-SCL |
3 Code Sample(1): Display System Info
When you run this code sample the system’s information will be listed on the OLED.
3.1 Hardware Connection
Connect the OLED module to the NEO-Hub’s I2C interface:

3.3 Run Code Sample
Before you run the code sample you need to follow the steps in bakebit tutorial to install the BakeBit package.
Enter the "BakeBit/Software/Python" directory and run the "bakebit_prj_SystemInfo.py" program:
cd ~/BakeBit/Software/Python sudo python bakebit_prj_SystemInfo.py
3.4 Observation
This is what users expect to observe:
4 Code Sample(2): UI Control via Joystick
A BakeBit - JoyStick module is needed in this test case. For more details about the joystick refer to the BakeBit - JoyStick page.
