The chip-on-back pad design and ultra-narrow PCB (41 × 12 mm) make it ideal for wearables, mini consoles, and space-constrained embedded projects where a small, clear display is needed.\n\nThe module features internal power-on reset, low power consumption (25 mA at full brightness), and compatibility with Arduino Uno, Leonardo, ESP32/ESP8266, and other 3.3–5 V microcontrollers. The rear solder pad design simplifies wiring for custom integrations.\n\nKey Features\n\n\n0.91-Inch OLED – 128×32 white self-illuminating pixels, no backlight required\n\nSSD1306 Driver – Widely supported with Arduino, CircuitPython, and MicroPython libraries\n\nI2C Interface – Only 4 wires (VCC, GND, SDA, SCL)\n\nChip-On-Back Pad Design – Rear solder pads for compact, custom mounting\n\nUltra-Narrow PCB – Just 41 × 12 mm, fits tight spaces\n\nLow Power – 25 mA full-screen on, 2 mA full-screen off\n\nInternal Power-On Reset – No external reset circuit needed\n\n\nSpecifications\n\n\nResolution – 128 × 32 pixels\n\nColour – White (monochrome)\n\nDriver Chip – SSD1306\n\nInterface – I2C\n\nOperating Voltage – 3.3–5 V\n\nBrightness – 180 cd/m² (typical)\n\nCurrent (Full On) – ~25 mA\n\nCurrent (Full Off) – ~2 mA\n\nOperating Temperature – −30 °C to +70 °C\n\nDisplay Area – 22.38 × 5.58 mm\n\nModule Dimensions – 41 × 12 mm\n\nWeight – 2.2 g\n\n\n\nNote: Turn off unused pixels when the display is idle to prevent uneven brightness from prolonged burn-in of static content.\n\n\nIdeal For\n\nWearable display devices\nMini game consoles and desktop widgets\nSensor readouts and status displays\nIoT devices with limited board space\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4104,"title":"Default Title","sku":"DF-DFR0647","price":16.77,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
