WF18GTZAADNN0
Overview
The WF18GTZAADNN0 is a 1.8-inch transmissive TFT LCD module from Winstar Display, featuring a resolution of 128 x 160 pixels. It utilizes the popular ST7735S controller and communicates via a serial SPI interface, making it suitable for low-pin-count microcontrollers. This full-color RGB display operates on a supply voltage between 2.5V and 3.7V, providing a compact visual interface for embedded systems.
Why Choose This Part
This module uses the ST7735S controller, which has extensive library support across most embedded platforms, including Arduino and ESP32. Its transmissive design combined with a white LED backlight ensures high visibility in indoor environments while maintaining a small 34mm x 45.83mm footprint. The 4-wire SPI interface reduces PCB complexity by requiring only a few GPIO pins for full-color operation.
Applications
Key Specifications
Getting Started
To interface with this display, ensure your microcontroller's logic levels match the 2.5V to 3.7V range or use appropriate level shifters. Libraries such as Adafruit_ST7735 are commonly used for rapid prototyping, allowing for easy drawing of text, shapes, and bitmaps. When wiring, pay close attention to the 10-pin module connector for the SPI signals (MOSI, SCK, CS) and the backlight power pins.
