It eliminates the need for contrast adjustment, retains backlight control, and is compatible with both 3.3 V and 5 V systems — making it a plug-and-play display for Arduino and other microcontroller projects.\n\nUsing I2C communication, the module requires just two data lines (SDA and SCL) plus power, freeing up GPIO pins for other components. The gray backlight gives a subtle, professional look compared to traditional green LCD modules.\n\nKey Features\n\n\n16×2 Character Display – Two rows of 16 characters for text, values, and status\n\nI2C Interface – Simple two-wire connection saves GPIO pins\n\n3.3 V and 5 V Compatible – Works with both voltage levels without level shifting\n\nNo Contrast Adjustment Needed – Pre-configured for optimal readability\n\nControllable Backlight – Gray backlight with software on/off control\n\nGravity Connector – Part of the DFRobot Gravity ecosystem for easy integration\n\n\nSpecifications\n\n\nOperating Voltage – 3.3–5.0 V\n\nOperating Current – ≤20 mA\n\nDisplay – 16×2 characters\n\nCommunication – I2C\n\nBacklight – Gray\n\nOperating Temperature – –20 °C to +70 °C\n\nStorage Temperature – –30 °C to +80 °C\n\nDimensions – 87.0 × 32.0 × 13.0 mm\n\n\nIdeal For\n\nDisplaying sensor readings and status information\nArduino and microcontroller projects needing text output\nBeginner electronics and STEM learning\nDashboards and monitoring displays\n\n\nResources\n\nProduct Wiki\nMore Documents\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5574,"title":"Default Title","sku":"DF-DFR0557","price":16.93,"on_sale":false,"in_stock":true,"available_quantity":67,"option1":"Default Title"}]}
