Key Features
- 24-Bit High Resolution: Captures extremely small weight changes, enabling gram-level and sub-gram accuracy depending on load cell quality.
- Selectable Gain (128/64/32): Channel A supports 128x or 64x gain for full-scale differential inputs of +/-20 mV or +/-40 mV; Channel B at 32x gain handles larger signals.
- Simple 2-Wire Digital Interface: Only two GPIO pins (DOUT and SCK) required - no SPI or I2C bus needed, freeing up communication peripherals.
- On-Board Voltage Regulator: Provides stable, low-noise excitation voltage to the load cell directly from the module, eliminating external regulator requirements.
- Low Power Consumption: Draws under 1.5 mA during operation with an automatic power-down mode when inactive, ideal for battery-powered projects.
- Integrated On-Chip Oscillator: No external crystal or clock source needed, reducing component count and PCB complexity.
- Wide Supply Voltage Range: Operates from 2.6V to 5.5V, making it compatible with both 3.3V and 5V logic microcontrollers.
- Simultaneous 50 Hz & 60 Hz Rejection: Built-in digital filtering suppresses power line noise for clean readings in any region.
- Breakout Header Pins: Pre-labeled E+, E, A+, A, B+, B pads for quick and reliable load cell wiring.

How It Works
The HX711 module acts as a bridge between an analog load cell and a digital microcontroller. A load cell is essentially a Wheatstone bridge of strain gauges that produces a tiny millivolt-level voltage proportional to the applied weight. The HX711 amplifies this minuscule signal using its programmable gain amplifier (PGA), then converts it to a 24-bit digital value using its internal sigma-delta ADC. Your microcontroller reads this digital value through a simple two-wire clock-and-data protocol. After calibration with a known weight, the raw ADC values are mapped to real-world weight units (grams, kilograms) in software.
