Pack of five 0.96″ OLED modules with 128×64 resolution, I²C interface, 3.3–5 V supply and SSD1306 driver for Arduino or Raspberry Pi projects
This pack contains five Hosyond B011 OLED modules, each with a 0.96 inch 128x64 pixel blue display driven by the SSD1306 controller. The I2C interface requires only two I/O pins and operates from 3.3V to 5V DC. Each board draws 0.04W during normal use and 0.08W with the full screen lit. They are aimed at makers building compact readouts for microcontroller projects.
These displays suit hobbyists adding status screens to Arduino Nano, R3, Mega, Raspberry Pi, 51 MCU or STM32 projects. The 128x64 resolution and monochrome blue output limit them to text, icons and simple charts. Projects needing colour, video playback, touch input or larger viewing areas should choose a different display technology.
The single specification that decides fit is the 128x64 pixel SSD1306 panel driven over I2C. This resolution and bus define the wiring, library support and graphics memory available. Verify your host has two free I/O pins and can supply 3.3V or 5V before purchasing.

Power the module at 3.3V–5V DC, run an I2C scanner to detect address 0x3C, then load a test sketch that fills the 128x64 pixel array; the blue self-luminous pixels should light without a backlight.
The box contains five 0.96" OLED modules with SSD1306 driver ICs in protective boxes; you must supply jumper wires, a 3.3V–5V microcontroller such as Arduino Nano, R3, Mega or Raspberry Pi, and a suitable library.
Choose the blue version listed here; its self-luminous pixels give ultra-high contrast and a viewing angle greater than 160°, making small fonts easy to read even in bright conditions.
