The HX711 Load Cell Amplifier acts as the bridge between your microcontroller and a load cell allowing you to measure weight with high accuracy. By reading subtle changes in resist ance this board enables you to create everything from industrial scales to simple process control systems (even a dog treat dispenser). We’ve updated this version specifically based on your feedback to ensure the cleanest possible data: Separated Supply Lines: Analog and digital supply lines have been decoupled to significantly reduce noise interference. Enhanced Filtering: A 3.3μH inductor and a 0.1μF filter capacitor have been added to the digital supply to stabilize measurements. Simple Interface & Wiring The HX711 uses a simple twowire interface (Clock and Data) that works with the GPIO pins of almost any microcontroller supported by widely available libraries (special thanks to Bodge!). The board is designed to accept the standard fourwire Wheatstone Bridge Configuration found on most load cells: Standard Pinout: Clearly labeled to match standard load cells: Red (Excitation+ or VCC) Black (Excitation or GND) White (Amplifier Signal or Output) Green (A+ S+ or O+) Yellow (Shield) EMI Protection: The YLW pin is an optional input that is not connected to the strain gauge and is used to ground and shield against external EMI (electromagnetic interference).
