Waveshare 1.8inch 128×160 SPI LCD Module

Waveshare 1.8inch 128×160 SPI LCD Module

Waveshare 1.8inch LCD Module is a general LCD display module with a 128×160 pixel screen and SPI communication. It is designed for embedded display projects that need a larger compact screen than sub-1inch modules while keeping wiring simple and controller integration straightforward.

The module integrates an ST7735S display driver, supports RGB 65K color, and works with 3.3V or 5V operating voltage. The SPI interface helps reduce GPIO usage, while the LED backlight makes it practical for device interfaces, status screens, compact dashboards, and controller panels.

Technical Specifications

Interface Notes & Hardware Guidance

• SPI wiring: Connect DIN and CLK to the controller SPI data and clock lines, then assign CS, DC, RST, and BL according to your firmware configuration.
• Voltage planning: The module supports 3.3V and 5V operation, but the connected controller and signal wiring should still be checked for logic-level compatibility.
• Driver support: Use ST7735S-compatible display libraries or Waveshare reference examples when integrating with Raspberry Pi, Arduino, STM32, or similar controllers.
• Backlight control: The BL pin can be used for backlight enable or brightness-control workflows depending on the host board and software setup.
• Mechanical layout: Confirm the module dimensions and mounting clearance against your enclosure or panel before final assembly.

FAQ

What display driver does this module use?

It uses the ST7735S display driver, so choose software libraries or examples that support ST7735S SPI LCD panels.

What resolution does the display provide?

The module provides a 128 x 160 resolution on a 1.8inch LCD display panel.

Does it use SPI communication?

Yes. The module communicates through SPI and uses control pins including CS, DC, RST, and BL.

Can it work with both 3.3V and 5V systems?

The official operating-voltage reference is 3.3V / 5V, but users should still verify host-board logic levels and wiring before integration.

Are development examples available?

Yes. Waveshare provides development resources and manual references for Raspberry Pi, Arduino, and STM32 workflows.
