Electrifier 1.3 Inch OLED Display Module 128×64 I2C Blue Pack of 2 | Two matched panels for dual readouts or a ready spare | 3.3V-5V input, onboard regulator | 4 mounting holes each

This Electrifier value pack puts two 1.3 inch OLED display modules in a single box, giving makers and product developers a matched pair to work with instead of a lone unit. Run both at once for projects that need two readouts, keep one as a ready spare on the bench, or split them across separate builds without placing a second order and waiting on shipping again. Across a 128x64 pixel grid, each panel renders sharp text, icons, small waveforms, and full menu screens for sensor values, clocks, network status, or a simple user interface in a compact footprint. Both units are monochrome blue OLEDs where every pixel emits its own light, so blacks stay genuinely dark and contrast holds up in dim rooms and under workshop lighting alike, with a wide off-axis viewing angle and no backlight to power. Each module communicates over a simple 4-pin I2C interface labelled VCC, GND, SCK, and SDA, so only the clock and data lines are needed alongside power and ground. In firmware, drive them with a graphics library that supports the module's controller, such as U8g2, which handles both SH1106 and SSD1306 devices from one library. An onboard low-dropout regulator on each board accepts any supply from 3.3V to 5V and connects directly to both 3.3V and 5V logic families without a separate level shifter, while four corner mounting holes per unit let you fix them to panels or enclosures. That makes the pair well suited to a wide range of 8-bit and 32-bit microcontrollers, development boards, and single-board computers with an I2C bus. Typical uses include IoT dashboards, temperature and humidity monitors, robotics and drone status screens, handheld instruments, retro-style mini games, and classroom prototyping where two students or two builds each need a screen. Both modules are produced through ISO-certified manufacturing and backed by a one-year Electrifier warranty, with clearly stated specifications so you know exactly what you are building with. For anyone who already knows they will need more than one screen, this two-pack is a straightforward way to buy the pair together.
