Displaytech 3.5" 320x240 TFT (DT035BTFT)
Overview
The DT035BTFT is a 3.5-inch color TFT display module with a 320 x 240 pixel resolution from Displaytech. It is intended for use as a compact graphical display in embedded products and prototypes. The module is suitable where a small color screen is needed for status, controls, or simple graphics.
Why Choose This Part
The 3.5-inch 320x240 format is a widely used compact size that balances readability and PCB space. That resolution is commonly supported by many graphics libraries and microcontroller drivers, simplifying software integration. The module form factor makes it straightforward to replace or upgrade displays during prototyping and product development.
Applications
Getting Started
Before connecting, obtain the vendor datasheet to confirm the display controller, interface (parallel, SPI, etc.), pinout, and supply requirements. Use a microcontroller or SBC with a matching interface and consider level shifting for logic-level mismatches and a proper backlight power supply. For software, common graphics stacks such as LVGL or Adafruit GFX (or vendor-provided drivers) are good starting points; verify or port a driver for the display controller listed in the datasheet.
