Description
Note: This TFT display has been discontinued. We recommend our newer 2.2″ TFT display available here. Please note it does not use the same wiring or controller and is not a drop-in replacement.
This 2.2″ 18-bit color TFT LCD display breakout board is an excellent choice to add a small, bright, vivid color display to your microcontroller projects. Utilizing the HX8340BN controller with built-in pixel-addressable video RAM, this display supports 220×176 resolution with 262,144 colors via 3-wire SPI communication.
The breakout board includes:
- 2.2″ diagonal TFT LCD with 18-bit color (220×176 pixels)
- HX8340B(N) controller with 9-bit SPI interface
- Built-in ultra-low-dropout 3.3V regulator and 3/5V level shifter for compatibility with 3.3V or 5V logic systems
- MicroSD card slot (not included) for loading full-color bitmaps (requires 2 additional digital lines)
- 3 white LED backlight with transistor for PWM dimming control
- 1×10 header for breadboarding and four 0.1″ mounting holes
- Overall dimensions: 43mm x 68mm x 6.5mm (1.7″ x 2.7″ x 0.25″)
Unlike CSTN type displays, this TFT offers high quality, fast refreshing color graphics. The open-source Arduino graphics library supports drawing pixels, lines, shapes, text, and bitmaps, with example code and wiring tutorials available.
