Frequently Asked Questions

Q: What is the difference between an OLED display module and a TFT LCD module?

A: OLED (Organic Light-Emitting Diode) display modules emit their own light per pixel, resulting in deep blacks, high contrast, and low power consumption — making them ideal for battery-powered Arduino or ESP32 projects. TFT LCD modules use a backlight with a colour filter, offering brighter, full-colour images at larger sizes. For example, the 0.85" TFT IPS LCD Display Module delivers vivid 65K colours, while OLED modules like the 0.49" OLED Display Module 64x32 SSD1306 excel in contrast and energy efficiency.

Q: Which communication interface should I use — I2C or SPI — for my display module?

A: I2C (IIC) requires only two data lines (SDA and SCL), making it great for projects where GPIO pins are limited, such as when using the 0.66" OLED Display Module for ESP32/WEMOS D1 Mini. SPI is faster and better suited for colour TFT displays or animations that require higher data throughput. The best choice depends on your microcontroller's available pins and the refresh speed your application demands.

Q: Are these display modules compatible with Arduino IDE and common libraries?

A: Yes! All display modules in this collection are compatible with the Arduino IDE. OLED modules based on SSD1306/SSD1315 drivers work with the widely-used Adafruit SSD1306 and U8g2 libraries, while colour TFT modules are supported by the TFT_eSPI and Adafruit GFX libraries. Simply install the relevant library via the Arduino Library Manager and you'll be up and running in minutes.

Q: Can I use these display modules with a Raspberry Pi or other single-board computers?

A: Absolutely. Most I2C and SPI display modules in this collection are compatible with Raspberry Pi and other single-board computers (SBCs). You can use Python libraries such as Luma.OLED for OLED screens or Pillow-based drivers for TFT displays, enabling seamless integration into Python-based embedded projects.
