Logic Level Serial Character LCD Displays

Our intelligent LCD modules offer versatile logic‑level serial communication—making them a robust and scalable solution for character display needs. Whether you require a compact 2‑line or an expansive 4‑line module, these displays offer flexible configurations, optional keypads, and a reliable packet‑based command set. Choose your preferred size, color, and interface, then explore the detailed data sheets for communication protocol and command definitions.

What Makes Them Stand Out

• Multiple interface configurations: Modules can be set to 6 different interfaces—including logic‑level serial—by adjusting jumpers or sending a configuration command.
• Precise packet communication: Use an error‑reducing, CRC‑protected packet protocol for reliable, noise‑resistant control—ideal for mission‑critical embedded systems.
• Modular line counts: Available in both 16×2 and 20×4 character configurations to suit simple UIs or dense informational displays.
• Optional keypad integration: Certain models include integrated keypads and function keys for direct user input—no additional hardware required.
• Backwards compatibility: Legacy serial support is built‑in, ensuring seamless integration when upgrading from earlier models.

Why These LCDs Make Sense

• Rapid development: Familiar command sets and multiple interfaces minimize time to prototype and deploy.
• Reduced wiring complexity: Serial communication lets you drive your display with fewer pins and simpler wiring harnesses.
• Industrial‑grade reliability: Packet‑based communication ensures commands only register when fully correct—no phantom inputs.
• Adaptable hardware: Flexible interface configuration makes these modules future‑proof and suitable for a range of platforms.
• Expert support: Responsive technical assistance and detailed documentation support your design process.
