The on-board MCU processes HX711 data and communicates via I²C, making it compatible with Arduino, micro:bit, ESP32, and Raspberry Pi.\n\nUnlike basic HX711 breakouts, this kit features a built-in calibration algorithm with one-button calibration — no separate calibration sketch needed. Simply press the button or use the API to calibrate, then start reading weight values over I²C.\n\nKey Features\n\n\n1 g to 1,000 g Range – Suitable for small-scale weighing applications\n\nHX711 ADC with On-board MCU – Processed data output via I²C for easy integration\n\nOne-Button Calibration – Built-in calibration algorithm, no separate code needed\n\nAPI Calibration – Alternatively calibrate programmatically via software\n\nGravity I²C Interface – Standard DFRobot Gravity connector with 3.3V/5V compatibility\n\nConfigurable I²C Address – 0x64, 0x65, 0x66, or 0x67\n\nComplete Kit – All mounting hardware and acrylic bracket included\n\n\nSpecifications\n\n\nMeasuring Range: 1 g – 1,000 g\n\nWorking Voltage: 3.3V / 5V\n\nWorking Current: <20 mA\n\nAD Conversion Chip: HX711\n\nCommunication: I²C\n\nSignal Board Size: 31 × 37 mm\n\nAssembled Dimensions: 120 × 100 × 30 mm\n\n\nCompatibility\n\nArduino (Uno, Mega, Leonardo, etc.)\nmicro:bit\nESP32\nRaspberry Pi\n\n\nIdeal For\n\nDIY electronic scales\nInventory and supply-level monitoring\nIoT weighing platforms\nSTEM education projects\n\n\nPackage Contents\n\n1× Weight sensor (load cell)\n1× Signal transfer board (HX711 + MCU)\n1× Acrylic bracket\n2× M4×20 screws\n2× M5×20 screws\n2× M3×8 screws and nuts\n4× Trapezoidal feet\n1× Gravity 4-pin I²C cable\n\n\nResources\n\nProduct Wiki (Documentation, Code Examples, Assembly Guide)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2594,"title":"Default Title","sku":"DF-KIT0176","price":42.68,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":322,"option1":"Default Title"}]}
