The Waveshare 0.85inch LCD Display Module is a compact, versatile, and vibrant display solution designed for a wide range of embedded electronics projects. Featuring a 0.85-inch IPS panel with a resolution of 128×128 pixels and support for 65K RGB colors, this module offers clear, colorful, and sharp visuals in a tiny footprint. Its SPI interface minimizes required IO pins, making it compatible with popular microcontroller boards like Raspberry Pi, Arduino, STM32, ESP32, RP2040, and Jetson series. This article explores the many possibilities and practical applications of the Waveshare 0.85inch LCD Display Module, including hardware integration, project ideas, programming tips, and development resources.
The Waveshare 0.85inch LCD Display Module is a small yet powerful display designed to fit into compact embedded systems where space is limited but display quality cannot be compromised. Its IPS panel technology ensures wide viewing angles and vivid color reproduction, making it ideal for displaying text, graphics, and animations with clarity. The 128×128 pixel resolution, while modest, is sufficient for many user interface elements and simple graphical outputs.
Designed with embedded developers in mind, this module integrates an embedded GC9107 driver and communicates via a 4-wire SPI interface. The SPI bus reduces the number of IO pins needed, which is a significant advantage for microcontroller projects with limited pin availability. The module comes with development resources and example codes for multiple platforms, accelerating the prototyping process.

The IPS panel technology ensures consistent color and brightness even at wide viewing angles. The embedded GC9107 driver supports RGB565 color format, which is standard for many embedded displays, providing smooth and vibrant color output. The SPI interface enables fast and efficient communication with microcontrollers while saving GPIO pins.
The Waveshare 0.85inch LCD Display Module is designed to work seamlessly with a variety of controller boards:
- Raspberry Pi (all models including Raspberry Pi Zero)
- Arduino (Uno, Mega, Nano, etc.)
- STM32 microcontrollers
- ESP32 and ESP32-S3
- RP2040 based boards (like Raspberry Pi Pico)
- NVIDIA Jetson Series
The module uses a 4-wire SPI interface, which includes pins for clock (SCL), data (SDA), chip select (CSX), and data/command control (D/CX). The reset pin (RESX) is used to initialize the display on power-up. This interface is widely supported and easy to implement on almost any microcontroller or single-board computer.
The module can be connected to the Raspberry Pi SPI pins:
- SCL to SPI Clock (GPIO11)
- SDA to SPI MOSI (GPIO10)
- CSX to SPI Chip Select (GPIO8)
- D/CX to any GPIO for Data/Command control
- RESX to any GPIO for Reset control
- Power the module with 3.3V and connect ground accordingly.
This setup allows the Raspberry Pi to control the display using SPI commands and libraries provided by Waveshare or third-party developers.
Arduino boards can interface with the module similarly:
- Use hardware SPI pins (e.g., MOSI, SCK, SS)
- Assign digital pins for D/CX and RESX
- Power the module at 3.3V (use level shifters if using 5V Arduino boards)
Example libraries and sample code are available to simplify initialization and drawing operations.
STM32 and ESP32 microcontrollers also support SPI communication natively. The module can be connected to SPI pins on these boards, and developers can use example code provided by Waveshare or community libraries to display graphics, text, and animations.
The compact size and colorful display of the Waveshare 0.85inch LCD Display Module make it suitable for numerous creative and practical applications:
Its small footprint and vibrant display are perfect for smartwatches, fitness trackers, or other wearable gadgets that require a clear user interface in a tiny package. The low power consumption and compact size help extend battery life while maintaining user-friendly visuals.
