Product Overview and Package Contents
The ELEGOO 0.96 Inch OLED Display Screen Module, Self-Luminous, SSD1306, 3PCS is manufactured by ELEGOO. Each screen provides 128×64 graphics using self-luminous pixels with no backlight. The listing is identified by ASIN B0D2RMQQHR and has a price of $9.99.
The package contains 3 OLED display modules for multi-device builds. It also includes 5 female-to-female and 5 male-to-female jumper wires. Controller boards, breadboards, and enclosures are not included.
Screen Layout and Display Characteristics
The screen features fixed yellow and blue display zones. The upper yellow band displays headings, alerts, or icons. The lower blue area presents sensor readings and menus.
Display colors are fixed directly by the OLED panel. The screen does not support programmable RGB settings. It also does not support touch input.
Each module provides clear 128×64 graphics for project monitoring. The layout helps users scan status updates quickly. It suits robot status panels, sensor dashboards, and classroom demos.
I2C Interface and Addressing Details
Each module uses a four-wire I2C connection to save controller pins. Pins connect to GND, VCC, SCL, and SDA according to the module labels. Builders scan the I2C bus to detect the default 7-bit address 0x3C.
The 0x78 PCB marking represents the corresponding 8-bit write-address format used by some documentation. Users must distinguish between these address representations during programming.
Connecting multiple displays on one I2C bus requires unique addresses where supported. If address changes are not possible, users need an I2C multiplexer. This setup allows independent screen management across devices.
Board Compatibility and Power Specifications
These OLED modules work with common 3.3 V & 5 V project platforms. They add visual feedback to compatible microcontrollers and single-board computers. Users can integrate them into diverse electronics builds.
Builders must check module pin order and supply voltage before powering. It is also important to verify I2C logic levels and pull-up voltage. Ensuring these values match prevents hardware configuration errors.
Software setup requires confirming the SSD1306 software configuration on your platform. Correct library settings help maintain stable display output. Proper configuration ensures seamless rendering across projects.
Positive Highlights from Customer Feedback
One reviewer noted that the ssd1306 driver worked smoothly with Zephyr. They praised the setup for being simple and offering fast refresh rates. Another customer appreciated using the U8g2 library with an Arduino Uno.
A buyer highlighted that the U8g2 ASCII driver worked well in systems with limited RAM. Another reviewer mentioned that individual plastic cases kept the displays safe during shipment. Reliable operation was also reported on stm32f103 hardware.
Customers liked the convenience of having three modules ready for multiple projects. Reviewers also found the display quality sharp and clear despite the small physical footprint. Simple four-wire connections made breadboard testing straightforward for users.
Public review analysis
One reviewer reported that the silk-screened I2C marking was confusing compared to the functioning address. Another customer noted that no documentation was included in the package. A buyer also felt surprised that the display was yellow and blue rather than solid blue.
An Australian reviewer pointed out that the package provided only two sets of four connecting wires for three displays. That same user observed that 10 K pullups were needed for proper operation. Another customer advised verifying microcontroller pinouts before mounting directly.
