Product features
High contrast: 2.42-inch 7-pin SPI interface OLED's self luminous
characteristics provide extremely high contrast and excellent
display effects.
Ultra thin and lightweight: Due to the self luminous principle of
OLED, there is no need for backlight, making the control board
thinner and lighter.
Low power operation: 2.42-inch OLED does not consume energy when
displaying black, which helps to reduce overall power consumption.
Wide viewing angle display: 2.42-inch OLED Provides a wide viewing
angle of over 170 °, ensuring clear viewing from different angles.
Fast response: 2.42-inch 7-pin SPI interface OLED's fast response
time is suitable for applications with dynamic images and fast
refresh.
Support SPI/I2C communication: compatible with two communication
protocols, convenient for connecting with various microcontrollers.
Software support
Provide comprehensive software development support, including:
Routine data: Provide sample code for platforms such as Raspberry
Pi, Arduino, STM32, ESP32, etc.
Communication Protocol: Provide implementation details for SPI and
I2C communication protocols.
Graphic library: supports basic graphic drawing and text display
functions.
Font support: Built in multiple fonts to meet the display needs of
different languages and characters.

Interface Pin Definition (Hardware connection)
| Pin | Symbol | Descriptions |
| 1 | GND | Ground of Logic Circuit |
| 2 | VDD | Power Supply for Logic |
| 3 | SCK | Serial clock input. |
| 4 | SDA | Serial data input. |
| 5 | RST | This pin is reset signal input. When the pin is low, initialization
of the chip is executed. Keep this pin pull high during normal
operation. |
6 | DC | This pin is Data/Command control pin. When the pin is pulled high
and serial interface mode is selected, the data at SDIN will be interpreted as data. When it is pulled low, the data at
SDIN will be transferred to the command register. |
| 7 | CS | Chip Select. Chip is selected when CS0 = “L” . |
