• HX711 IC: Weight items accurately; Note: Some calibration required
• Separated analog and digital supply: VCC analog voltage to power the load cell; VDD digital supply voltage used to set the logic level
• Two-wire interface (Clock and Data): communication with a microcontroller GPIO pins; Numerous libraries written: for easy-to-read data from the HX711
• Operation Voltage: 2.7V--5V: Allows wide range of microcontroller compatibility; Operation Current: < 1.5mA
• Connect using Wheatstone bridge configuration: Mostly standard Four-wire connection to load cells; Selectable 10SPS or 80SPS output data rate; Simultaneous 50 and 60Hz supply rejection
