Waveshare 1.9-Inch SPI LCD Display Module 170×320 IPS Screen with 262K Colors for Microcontrollers and DIY Electronics

 Description:

The Waveshare 1.9-inch IPS LCD Display Module is a compact, high-quality display designed for embedded applications and DIY electronics. Featuring a 170×320 pixel resolution, 262K vivid color output, and wide viewing angles, this module delivers crisp, vibrant visuals ideal for user interfaces, IoT dashboards, and portable devices.

Built around the ST7789V2 controller, the display supports RGB input formats of 12-bit (RGB444), 16-bit (RGB565), and 18-bit (RGB666), offering flexibility in color depth. The SPI interface (4-wire) ensures fast communication with minimal GPIO usage, making it perfect for microcontrollers like Arduino, Raspberry Pi, STM32, and ESP32-based projects.

The display can be initialized in both portrait and landscape orientations, and although the internal controller supports 240×320 resolution, the actual active area is 170×320, allowing efficient use of memory and resources. The commonly used RGB565 format is featured in the demo for optimal performance and compatibility.

This module is an excellent choice for developers seeking a reliable, energy-efficient, and visually rich LCD for compact embedded systems.
