Product Details
2.23 Inch OLED Display 128x32 Pixels Product Introduction
SFOS223XZ-12832PA-N is a 2.23-inch OLED display module with a
128x32 dot matrix PMOLED screen and SSD1305 driver. It typically
has the following features:
- Display size and resolution: This module has a display size of 2.23
inches and a resolution of 128x32 pixels, suitable for application
scenarios that require clear display of small-sized text and
images.
- Driver chip: SSD1305 is a commonly used OLED driver chip that
supports multiple display modes and interfaces, including SPI and
I2C, providing stable display performance.
- Interface type: This module typically provides a 24 pin interface
and supports multiple communication protocols such as SPI and I2C,
making it easy to connect and transfer data with different
microcontrollers.
- Display color: Generally monochrome display, such as white, blue or
yellow, but in some models, dual color display can also be achieved
through special driving methods.
- Working voltage: Usually operates at 3.3V, compatible with 3.3V and
5V level logic, without the need for additional level conversion
chips.
- Power consumption: OLED display modules are known for their low
power consumption characteristics, especially when displaying in
full black, they consume almost no power.
- Perspective: Provides a super large viewing angle greater than 160
°, ensuring good visual effects from different angles.
- Working temperature: Industrial grade products usually have a wide
working temperature range, such as -40 ℃~85 ℃, suitable for use in
various environmental conditions.
- Hardware configuration: The module defaults to SPI communication
mode at the factory. If I2C communication mode is required, simple
hardware modifications may be necessary.
- Software support: Provides sample programs for various platforms
such as Raspberry Pi, STM32, Arduino, etc., making it easy for
developers to quickly get started and develop.
- Application scenarios: Suitable for various systems that require
HMI, such as IoT devices, information and entertainment products,
industrial sites, and military industries.
In practical applications, you may need to write or use existing
libraries to initialize the display module, set display parameters,
and send data to the display module to display graphics or text.
For example, you may need to set display area, clear screen, draw
points or lines, etc. When choosing an OLED display module, factors
such as power consumption, resolution, interface type, display
color, operating voltage, and temperature range should be
considered to ensure that it meets specific application
requirements.
