Most follow a standard 14 or 16-pin layout, but always verify the pinout, as some manufacturers swap pins or change backlight connections.

Engineering-grade character and numeric displays for embedded HMI
What are Character & Numeric Display Modules components?
Character and numeric modules provide essential HMI for embedded systems. Select based on interface (I2C/SPI/Parallel), supply voltage, and environmental requirements. OLEDs offer superior contrast and viewing angles, while LCDs remain the standard for low-power, sunlight-readable applications.
How to Choose Character & Numeric Display Modules Components
Selecting the right module requires balancing interface constraints with environmental and power requirements.
Interface Protocol
Determine if your MCU supports parallel (4/8-bit), I2C, or SPI. I2C/SPI saves pins but may require specific controller support.
Display Technology
Choose OLED for high contrast and wide viewing angles, or LCD (STN/FSTN) for lower power consumption and sunlight readability.
Supply Voltage
Verify if the module requires 3.3V or 5V logic and if the backlight requires a separate power rail.
Mechanical Footprint
Check mounting hole patterns and bezel dimensions to ensure compatibility with your enclosure design.
Temperature Range
Industrial applications often require extended temperature ranges (-20°C to +70°C) to prevent ghosting or failure.
