## Description

The Adafruit HX711 Breakout is a high-resolution 24-bit differential ADC designed for reading load cells, strain gauges, and other Wheatstone bridge sensors. With selectable 64× or 128× gain on Channel A and fixed 32× gain on Channel B, it amplifies the tiny voltage changes from bending or twisting sensors and converts them into precise digital readings for force or mass measurement. The breakout uses a two-wire protocol (similar to SPI) and comes with pre-soldered 6-port terminal blocks for connecting one or two 4-wire sensors. A slide switch lets you select between 10 SPS and 80 SPS sampling rates. Arduino and CircuitPython libraries are available for quick setup. Key Features 24-Bit Differential ADC – High-resolution readings from Wheatstone bridge sensors Dual Channel Input – Channel A with selectable 64× or 128× gain, Channel B with fixed 32× gain Pre-Soldered Terminal Blocks – 6-port connector for easy sensor wiring (E+, E-, A+, A-, B+, B-) Selectable Sample Rate – Slide switch for 10 SPS or 80 SPS Two-Wire Interface – SPI-like protocol for communication with any microcontroller Split Analog/Digital Supply – With digital supply filtering for clean readings Arduino and CircuitPython Support – Ready-to-use library and example code Ideal For Digital scales and weight measurement Load cell and strain gauge applications Force and pressure sensing projects Industrial measurement and monitoring Package Contents 1× Adafruit HX711 Breakout Board – Assembled with pre-soldered terminal blocks Note: This sensor has a fixed I²C address. If you need multiple sensors on one bus, a multiplexer is required. Load cells and strain gauges are not included. Tip: If you prefer an I²C interface with STEMMA QT connectors instead of the two-wire protocol, check out the Adafruit NAU7802 24-Bit ADC.
