Oled display 128 x 32 - I2C

Product Description

The 0.91-inch OLED I2C display, with a resolution of 128x32 pixels, is a compact module designed for use with Arduino, Raspberry Pi, and other microcontrollers.

Key Features:

• High Contrast Display: The OLED screen provides excellent readability due to its high contrast, with self-illuminating pixels that eliminate the need for a backlight, thus contributing to low power consumption.
• Compatibility with Microcontrollers: This versatile display is ideal for a wide range of microcontrollers, including ESP32, ESP8266, STM32, AVR, DSP, ARM, PLC, TTL logic, etc.

It is controlled via the I2C interface, requiring only 4 connection pins.

Technical Specifications:

• PCB Size: 38x12mm
• Screen Size: 30 x 11.5mm
• Active Display Area: 26 x 9.5mm
• Dot Matrix: 128 x 32
• Pixel Size: 0.152 × 0.152 mm
• Pixel Pitch: 0.175 × 0.175 mm
• Display Mode: Passive matrix
• Display Supply Voltage: 3.3V - 5V

Arduino IDE Connection Example:

To complete this example, you will need the following:

1x GroundStudio Jade N1 development board || Reference LTAYNO_AAA

1x OLED Display 128x32 - I2C || Reference OLED-12832

Step 1 - Download Arduino IDE

Arduino IDE

Before connecting the board, start by downloading Arduino IDE 1.8.x from the link above, according to your preferences and the operating system used.

Step 2 - Connect the development board to the computer

After the initial connection via a USB-C cable, the computer will try to find a compatible driver. In this case, it will connect directly to Windows using the HT42B534-2 chip as the drivers for this chip will install automatically.

Step 3 - Configure Arduino IDE Settings

To select the board, go to the "Tools" menu, then click on the board button, making sure that "Arduino Nano" is selected.

After selecting the board, a new section "Processor" will appear in the Tools menu. Here, you will need to select the "ATmega328P" option.

Next, we need to tell the Arduino IDE to which of our computer's serial ports the Jade N1 is connected. To do this, go again to "Tools," then select the COM port of Jade N1.

If you have multiple ports and are unsure which port is Jade N1, disconnect it briefly and check the "Ports" menu in "Device Manager" to see which one disappears.

After selecting the Port and Board, you need to install the required library for the display.

Select Tools -> Manage Libraries... and in the window that appears, search for and install "Adafruit SSD1306".

You can now upload the test code from the menu File -> Examples -> Adafruit SSD1306 -> ssd1306_128x32_i2c.

After loading the code, a series of images will be displayed on the screen as shown in the photos below:
