128×64 3.6 inch ST7588 I2C Graphics Display Module

Product Description

The UGE ST7588i LCD Module is a high-quality 3.6-inch 128×64 dot matrix graphic display featuring a vivid orange background and dark pixel contrast.
Powered by the reliable ST7588i controller, it provides a crisp and stable image with low power consumption — ideal for embedded applications, measurement instruments, control panels, and custom electronics.

This module communicates via a 2-wire I²C interface, reducing wiring complexity and making it perfectly compatible with Arduino, ESP32, STM32, AVR, and most modern microcontrollers.

The module includes on-board voltage selection jumpers for 3.3 V or 5 V logic, reset pin, and optional backlight control, making integration effortless for both beginners and professionals.

Sample Arduino Test Code

Library required:Install U8g2 by olikraus from Arduino Library Manager.

#include <Arduino.h>
#include <U8g2lib.h>
#include <Wire.h>

// Create display instance for your module
U8G2_ST7588_JLX12864_1_HW_I2C u8g2(U8G2_R2, /* reset=*/ U8X8_PIN_NONE);

void setup() {
u8g2.begin();
u8g2.setContrast(150); // Adjust brightness if needed
}

void loop() {
u8g2.firstPage();
