Product OverviewStreamline your next project’s display with our 16×2 LCD Display Module and I²C Interface Adapter. Delivering crystal-clear text, low-pin-count wiring, and broad compatibility, this duo is perfect for Arduino, Raspberry Pi, and other microcontroller applications from simple readouts to sophisticated industrial controls. Key Features & Benefits Vibrant 16×2 Character Display• Blue LED backlight with adjustable contrast for crisp, easy-to-read characters in any lighting. Wide Viewing Angle & High Contrast• Readable from nearly 180°, ensuring information is visible from multiple positions. HD44780-Compatible Controller• Plug-and-play compatibility with established libraries and code examples. 4-Wire I²C Interface• Reduces GPIO usage from seven pins to just two (SDA, SCL), plus power and ground. Expandable I/O• Frees up pins for sensors, SD cards, relays, and more ideal for complex, multi-sensor systems. Standard 5 V Operation• Powers directly from most development boards without level shifting. Compact Footprint• Module: 80 × 35 × 11 mm; Viewing area: 64.5 × 16 mm fits neatly into tight enclosures.
