Description

The 1.69-inch IPS TFT LCD Display Module is a high-quality color display designed for embedded systems and development boards. Featuring a 280 × 280 resolution and 16-bit RGB color support (65K colors), it provides sharp visuals and vibrant color reproduction.

The display uses the ST7789 driver IC, communicating through a 4-wire SPI interface, making it easy to integrate with microcontrollers such as ESP32. The module also includes a capacitive touch panel controlled by the CST816S touch controller, enabling interactive user interfaces for modern embedded projects.
