HX711 24-Bit Load Cell Weighing Module with 4-Digit Display — 4-Key, 5V, 55×35mm

HX711 24-Bit Load Cell Weighing Module with 4-Digit Display — 4-Key, 5V

This HX711 weighing module integrates a 24-bit HX711 ADC, a 4-digit 7-segment LED display, and 4 function keys on a single 55×35mm PCB, providing a complete standalone digital scale solution. Connect four 350Ω load cells in a Wheatstone bridge configuration, power with 5V DC, and the module displays weight directly — no Arduino or external MCU required for basic weighing operation.
