Overview
The 1.77" SPI TFT Display is a color LCD module with 128x160 pixel resolution, driven by the ST7735 controller. Unlike monochrome OLED modules, this TFT display supports 65K colors (RGB565), enabling full-color graphics, images, and rich user interfaces. It communicates over the SPI bus for fast data transfer.
Key Features
- Full color display — 65K colors (16-bit RGB565) for graphics and images
- ST7735 driver — widely supported color TFT controller
- SPI interface — fast data transfer for smooth screen updates
- 128x160 resolution — suitable for color UI elements and small images
- Backlit LCD — readable in various lighting conditions with LED backlight
Typical Applications
- Color dashboards for IoT projects
- Mini photo frames and image viewers
- Game consoles and retro gaming displays
- Graphical menu systems
- Color data visualization (charts, gauges)
- Camera viewfinders and preview screens

SPI vs I2C
This display uses SPI rather than I2C, which provides significantly faster data transfer — important for color displays that need to push 16 bits per pixel. The tradeoff is more wiring (6-8 pins vs 4), but the performance gain is essential for smooth color graphics.
