2-inch LCD Display Module Product Overview
The Waveshare 2-inch LCD Display Module is a 2-inch IPS full-color LCD display module with 240×320 resolution and 262K color support. It features an embedded ST7789VW driver chip and communicates via a 4-wire SPI interface. The module operates with both 3.3V and 5V logic levels, with a display area of 30.60×40.80mm, module dimensions of 58×35mm, and pixel pitch of 0.1275×0.1275mm. It offers low power consumption and a simple interface that effectively saves GPIO resources on the host controller. Comprehensive development resources are provided, including example programs for Raspberry Pi, VisionFive2, Arduino, and STM32 platforms, making it suitable for embedded displays, sensor data visualization, IoT status panels, and portable instruments.

FAQs:
Q: What host platforms are compatible?
A: The module is compatible with both 3.3V and 5V logic, directly connectable to Raspberry Pi, VisionFive2, Arduino, STM32, and other mainstream boards. Waveshare provides complete example code for these platforms, including BCM2835 library, WiringPi library, Python demos, Arduino demos, and STM32 demos.
Q: What are the pin functions of the 8-pin interface?
A: VCC (3.3V/5V power), GND (ground), DIN (SPI data input), CLK (SPI clock), CS (chip select, active low), DC (data/command, low for command, high for data), RST (reset, active low), BL (backlight control).
Q: How does the ST7789VW driver chip perform?
A: The ST7789VW is a single-chip TFT-LCD controller/driver supporting 262K colors, with 240 source lines and 320 gate line driving circuits, communicating via 4-wire SPI and supporting RGB565 color format.
Q: Does the module support backlight adjustment?
A: Yes. The BL pin controls the backlight, and PWM signals can be used for brightness adjustment.
