Overview

Product Overview

A large-format load cell amplifier module using the HX711 24-bit ADC. Presoldered for quick integration. Ideal for scales, force measurement, and weight sensing projects with Arduino and microcontrollers.

The HX711 is a 24-bit analog-to-digital converter purpose-built for weigh scales: it amplifies the tiny signal from a standard 4-wire bridge load cell and returns a clean digital reading over a simple two-pin (DT/SCK) interface. Two differential input channels are available - channel A with selectable gain of 128 or 64 for the load cell, and channel B at gain 32.

This large-format board brings the pre-soldered header and connection pads out on a roomier PCB that is easier to mount and wire in enclosures. Well-supported libraries exist for Arduino, ESP32, and Raspberry Pi Pico, so you can build kitchen scales, force gauges, filament weight monitors, and beehive or inventory scales quickly.

Questions & answers

Frequently asked questions

Yes. This HX711 load cell amplifier is intended for Arduino and other microcontrollers, and can be used with Raspberry Pi GPIO through suitable software. You still need a compatible load cell and calibration code for accurate readings.
Yes. The module is pre-soldered so it can be wired into a project without soldering the header pins first. Connect the load cell and microcontroller wiring, then run an HX711 library or sketch to calibrate it.
The HX711 uses a 24-bit ADC to digitize the tiny signal from a strain-gauge load cell. It communicates with a microcontroller over digital data and clock lines rather than providing a simple analog voltage output.
Yes. Pair it with a suitable load cell, a stable mechanical platform, and an Arduino or similar controller to build a digital scale. It is also useful for force measurement and weight-sensing projects.
Unstable readings are usually caused by incorrect load cell wiring, missing calibration, loose connections, electrical noise, or mechanical movement in the scale frame. Verify the load cell wiring, keep connections secure, and calibrate with a known weight.
