Electrifier 0.91 Inch OLED Display Module 128×32 SSD1306 I2C, Blue

• Compact Project Interface — Fits a readable status screen into breadboard prototypes and small enclosures, showing live sensor readings, menu text and counters where a full-size panel simply will not physically fit.
• 128 By 32 Pixel Matrix — Renders multi-line text, simple icons and small bitmap graphics across the full 0.91 inch active area, so numeric readouts stay legible without scrolling every value past the viewer.
• SSD1306 Driver On Board — The panel is driven by the widely supported SSD1306 controller, so it works with standard open-source SSD1306 graphics libraries and existing example code needs little or no rewriting.
• Four Wire I2C Connection — Ground, VCC, SCK clock and SDA data pads run on the two-wire I2C serial bus from a 3.3V to 5V supply, leaving the remaining input and output pins on the controller board free.
• Self Emissive Blue Panel — Each pixel makes its own light, so unlit pixels stay truly dark with no backlight glow, and only the illuminated pixels draw current, which suits battery powered portable builds.
• Small Footprint And Loose Header — The module measures 3 x 1 x 1 cm and weighs 5 grams, and ships with a 4-pin header supplied loose, so the pads can be soldered straight or right-angle to suit the build.
• Backed By Electrifier Assurance — Supplied with a 1 year warranty and sourced under ISO 9001:2015 certified quality processes, with Indian after-sales support for replacement and technical queries.

The Electrifier 0.91 inch Blue OLED Display Module is a small single-colour panel for builds that need a readable status readout without a full-size screen. Across a 128 by 32 pixel matrix it renders multi-line text, counters, sensor values, simple icons and small bitmap graphics, which makes it a practical front end for temperature loggers, battery monitors, timers, handheld test gear and panel-mounted controls inside compact enclosures.

The panel is driven by the SSD1306 controller and communicates over the two-wire I2C serial bus, so it works with the standard open-source SSD1306 graphics libraries. Four through-hole pads marked ground, VCC, SCK and SDA carry the connection, with VCC accepting a 3.3V to 5V supply, so the module suits both 3.3V and 5V controller boards without a level shifter. Because the display shares a single I2C bus with other sensors and peripherals, the remaining input and output pins stay free for relays, buttons and analogue inputs.

Being an organic light emitting diode panel, each pixel produces its own light through electroluminescence. There is no backlight layer behind the glass, which keeps the module thin and lets unlit pixels read as true black rather than the washed grey typical of a lit character LCD. Only the illuminated pixels draw current, so a mostly dark screen consumes less power than a comparable backlit display, which matters in battery powered instruments and portable projects.

The module measures 3 x 1 x 1 cm and weighs 5 grams, and is supplied with a 4-pin header packed loose so it can be soldered straight or right-angle to match the enclosure. It sits alongside the wider Electrifier display range, which covers 0.96 inch and 1.3 inch I2C panels as well as SPI and round TFT options, so a project can scale up in size without changing its wiring approach.

Every unit carries a 1 year warranty, is sourced under ISO 9001:2015 certified quality processes and is supported in India for replacement and technical queries.
