0.96 Inch OLED Display Module

DescriptionThe 0.96 Inch I2C OLED Display is a compact, ultra-bright, and low-power display module that brings a sharp visual output to any microcontroller project using just two wires — SDA and SCL. Based on the popular SSD1306 driver chip with a 128×64 pixel resolution, this display is perfect for showing sensor readings, status messages, menus, icons, and real-time data in your Arduino, ESP32, or ESP8266 projects.Unlike LCD displays that require a backlight and multiple data wires, this OLED display emits its own light from each pixel — making it crisper, more energy-efficient, and visible even in direct sunlight. Available in Blue or White pixel colour depending on stock, it is one of the most widely used displays in Bangladesh for IoT projects, robotics, and learning electronics.⭐ Key Features��️128 × 64 Pixel ResolutionSharp crisp display — fits multiple lines of text, icons and graphs��I2C Interface — Only 2 WiresSDA SCL only — frees up all your other GPIO pins for sensors��Self-Emitting OLED PixelsNo backlight needed — each pixel glows itself, visible in any light��Ultra Low PowerOnly 20mA typical — ideal for battery-powered IoT projects��3.3V and 5V CompatibleWorks with both 3.3V and 5V boards — Arduino, ESP32, ESP8266��Compact 0.96 Inch SizeTiny footprint — fits into small enclosures and wearable builds�� What Can You Display on This OLED?��️Sensor ReadingsTemperature, humidity, pressure and gas values��Live Data GraphsReal-time data visualisation and progress bars��Status & MenusSystem status messages and navigation menus��Robot DisplayShow robot state, speed, battery and direction⌚DIY Clock & TimerDigital clock, countdown timer and stopwatch projects�� Who Should Buy This?�� BeginnersLearning Arduino or ESP32?

Both are free and installed directly from Arduino IDE in under 2 minutes.⚠️ Most Common Issue — Display Shows Nothing: The default I2C address used in most examples is 0x3C. If your display stays blank, try changing the address to 0x3D in your code. You can also run an I2C scanner sketch to confirm your display’s address — see Step 3 below.1Install Adafruit SSD1306 LibraryOpen Arduino IDE → Sketch → Include Library → Manage Libraries → Search Adafruit SSD1306 → Click Install. When prompted, also install all dependencies including Adafruit GFX Library.2Wire the DisplayConnect 4 wires only — VCC → 3.3V or 5V, GND → GND, SDA → SDA pin (A4 on Arduino Uno, GPIO21 on ESP32), SCL → SCL pin (A5 on Arduino Uno, GPIO22 on ESP32).3Confirm Your I2C AddressNot sure which address your display uses? Go to File → Examples → Wire → i2c_scanner and upload it. Open Serial Monitor at 9600 baud — it will print the exact I2C address of your display (usually 0x3C or 0x3D).4Run the Example SketchGo to File → Examples → Adafruit SSD1306 → ssd1306_128x64_i2c. Make sure the address in Adafruit_SSD1306 display(128, 64, &Wire, -1) matches your display. Upload and watch the demo run on screen.�� Wiring Reference — OLED to Common BoardsOLED PIN → BOARD PIN CONNECTIONSOLED PinArduino UnoESP32ESP8266VCC5V or 3.3V3.3V3.3VGNDGNDGNDGNDSDAA4GPIO21GPIO4 (D2)SCLA5GPIO22GPIO5 (D1)�� Quick Start — Example Code��️Example 1 — Display Hello World Text#include <Wire.h> #include <Adafruit_GFX.h> #include <Adafruit_SSD1306.h> // Define display dimensions #define SCREEN_WIDTH 128 #define SCREEN_HEIGHT 64 #define OLED_RESET -1 // No reset pin #define I2C_ADDRESS 0x3C // Try 0x3D if blank screen Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET); void setup() { Serial.begin(115200); if (!display.begin(SSD1306_SWITCHCAPVCC, I2C_ADDRESS)) { Serial.println("SSD1306 not found!

(2) I2C address — run the i2c_scanner sketch to confirm whether your display is at 0x3C or 0x3D, then update your code. (3) Library — make sure both Adafruit SSD1306 and Adafruit GFX are installed. These three steps fix 99% of blank screen issues.❓ Can I connect multiple OLED displays to the same board?Yes — since I2C supports multiple devices on the same bus, you can connect two OLED displays at the same time if they have different I2C addresses (0x3C and 0x3D). On some displays there is a solder bridge on the back to change the address from 0x3C to 0x3D.❓ Which library should I use for this OLED with Arduino?Use the Adafruit SSD1306 library together with Adafruit GFX Library — both available directly in Arduino IDE Library Manager. For ESP32 and ESP8266 projects, the same libraries work without any changes.❓ Does this OLED work with ESP32 and ESP8266?Yes — the 0.96 inch I2C OLED display works with Arduino, ESP32, ESP8266, STM32, and Raspberry Pi Pico. Just connect SDA and SCL to the correct I2C pins of your board (see wiring table above) and use the Adafruit SSD1306 library.❓ What is the 0.96 Inch OLED Display price in Bangladesh?The 0.96 Inch I2C OLED Display price in BD is 339 BDT from Dream RC — the best price available in Bangladesh with genuine SSD1306 module, fast delivery, and Cash on Delivery support nationwide.�� Compatible Development Boards ESP32-C3 Super MiniThe most compact pairing — connect the OLED to the ESP32-C3 Super Mini via GPIO8/9 for an ultra-small IoT display node that fits inside the tiniest enclosures.
