- TypeSingle Board Computers
- Five displays per pack for multiple projects
- 91 inch 128x32 OLED shows crisp white text
- SSD1306 driver with I2C needs only two data lines
- Works at 3.3V or 5V with ESP32 ESP8266 STM32
- Self-luminous panel uses no backlight saving battery power
Five OLED modules in one pack
This pack supplies five 0.91 inch OLED modules, each with a 128x32 white-text display and an integrated SSD1306 driver. The boards are intended for makers, students and engineers building sensor nodes, status panels or wearable prototypes that need a compact self-illuminating screen.
Low power draw and simple wiring
The self-luminous panels operate without a backlight, which keeps current draw small for battery-powered devices. Communication uses a standard I2C bus needing only two data lines plus power, so the modules add minimal load to a microcontroller's pins and thermal budget.
Replaces bare LCDs or single-module purchases
Builders who previously used character LCDs gain higher contrast and wider viewing angles without extra wiring. The five-unit bundle suits projects that need several identical displays at once, while single-display experiments are better served by individual boards.

Soalan tentang produk ini
How do I wire the 4-pin I2C interface on the 0.91 inch SSD1306 board and which step causes the display to stay blank?
Connect VCC to 3.3 V or 5 V, GND to ground, SDA to the data line and SCK to the clock line; the common mistake is swapping SDA and SCK, which prevents any communication.
What component will degrade first and require module replacement during long-term use?
The self-illuminating OLED pixels gradually lose brightness; once white text becomes too dim to read, the entire 128x32 module must be replaced.
What is the first limitation that appears when the display runs continuously at 5 V?
The 128x32 pixel array can only show a small amount of text at once, so sustained logging quickly fills the screen and forces scrolling or clearing.
