Frequently Asked Questions
Q: What is the difference between an OLED display module and a TFT LCD display module?
A: OLED display modules emit their own light per pixel, resulting in deep blacks, high contrast, and very low power consumption — ideal for battery-powered Arduino or ESP32 projects. TFT LCD display modules use a backlight behind a liquid crystal panel, which typically allows for larger sizes, full-color output, and higher brightness. For color-rich UIs, consider a TFT LCD such as the 1.14 Inch IPS TFT LCD Color HD Display Module; for simple, power-efficient readouts, an OLED module is often the better choice.
Q: Are these display modules compatible with Arduino and ESP32?
A: Yes! All display modules in our collection are compatible with popular development boards including Arduino Uno, Arduino Nano, ESP32, ESP8266, and Raspberry Pi. They use standard I2C or SPI interfaces and are supported by widely available open-source libraries such as Adafruit SSD1306, Adafruit GFX, and TFT_eSPI, making integration straightforward for both beginners and experienced makers.
Q: What does I2C vs. SPI mean for display modules?
A: I2C display modules (like most of our SSD1306 OLED displays) use just two data lines (SDA and SCL), making wiring simple and freeing up pins on your microcontroller — great for compact builds. SPI display modules (like our ST7789 TFT LCD screens) use more lines but offer faster data transfer, which enables smoother graphics and higher frame rates. Choose I2C for simplicity and pin conservation, and SPI for speed and rich graphical content.
Q: What voltage do these display modules operate at?
A: Most display modules in our collection operate at 3.3V or 5V, and many include onboard voltage regulators to accept both. For example, our 0.96" OLED I2C Display Module SSD1306 128x64 for Arduino ESP32 supports 3.3V–5V operation, making it safe to use directly with both 5V Arduino boards and 3.3V ESP32/ESP8266 boards without additional level-shifting hardware. Always check the individual product listing for voltage specifications before wiring.
