An LCD module is the window to your microcontroller's soul, allowing real-time debugging and user interaction. SunFounder LCD display modules are built for ease of use. Our popular I2C LCD screens reduce wiring complexity from 16 pins down to just 4, making them perfect for clean prototyping. Whether you need to display simple text strings or complex sensor readings, our reliable hardware and extensive code libraries (C++ and Python) ensure you get up and running quickly.
○ Character LCDs (1602/2004): The standard for displaying text and numbers. Best for weather stations, clocks, and simple status monitors.
○ Graphic LCDs & OLEDs: When you need to show charts, icons, or custom fonts, our pixel-based LCD arduino displays and OLED modules offer higher resolution and better contrast.
○ Touch & TFT Shields: For interactive interfaces, explore our color TFT shields that plug directly onto your Arduino board.
○ What is an I2C LCD module?
Standard LCD modules require many pins to operate. An I2C adapter (backpack) soldered onto the back allows you to control the screen using only 2 data pins (SDA and SCL), which is a huge advantage when working with boards like the Arduino Uno.
○ Do you provide libraries for these screens?
Yes, we provide download links for standard libraries (like LiquidCrystal_I2C) and example sketches in our Wiki to help you print "Hello World" on your LCD screen in minutes.
○ Can I use these displays with a Raspberry Pi?
Absolutely. Our LCD modules are compatible with Raspberry Pi via the GPIO pins or I2C interface. We provide Python scripts to drive the displays easily.
