3.5 Inch Color TFT LCD Display Screen Module 320x480
Image Gallery
Overview
The DIYables 3.5 Inch Color TFT LCD Display Module delivers 320×480 pixel HVGA resolution with 262K colors (18-bit) using the ILI9486 driver over an 8-bit parallel interface. The shield form factor plugs directly onto Arduino-compatible boards without breadboards or complex wiring. It is a non-touch display optimized for graphics-intensive applications such as data dashboards, weather stations, gaming, and control panels. Active area is 73mm × 48.96mm on an ~85mm × 55mm PCB.

Beginner Tutorials
Notes
- The 8-bit parallel interface is faster than SPI but uses more MCU pins.
- This is a non-touch variant — for touch control, see the 3.5" Touch Shield.
- Specify ILI9486 driver type when initializing the library.
