128x64 pixels OLED Shield with I2C. It adds a 128x64 monochrome OLED to ESPea main board.
The OLED uses only the two I2C pins on the ESPea, and you can pretty much stack it with ESPea, even ones that use I2C since that is a shared bus.
- Screen Size: 128x64 pixels (0.96” Across)
- Operating Voltage: 3.3V
- Driver IC: SSD1306
- Interface: IIC(I2C)
- IIC Address: 0x3C or 0x3D
I2C Data Pins
- SCL - D1
- SDA - D2
These pins can be shared with other I2C devices.
The I2C address is 0x3D and can be changed by jumper. (See the label at PCB)
Work with Arduino
- Install Library Adafruit_SSD1306 with Library Manager (Sketch -> Include Library -> Manage Libraries)
- Test example sketch
