## Description

The Adafruit NAU7802 is a high-resolution 24-bit differential ADC breakout designed specifically for reading strain gauges, load cells, and other Wheatstone bridge sensors. With built-in gain amplification and calibration circuitry, it converts the tiny voltage changes from bridge sensors into precise digital readings over I2C. The breakout includes screw terminal blocks for connecting 4-wire sensors: E− (ground), E+ (configurable reference voltage from 2.4–4.0 V), and A−/A+ differential inputs. STEMMA QT / Qwiic connectors provide solderless I2C wiring to your microcontroller. Key Features 24-Bit Differential ADC – Ultra-high resolution for precise strain and force measurements Built-In Gain & Calibration – Configurable gain and on-chip calibration for Wheatstone bridge sensors Configurable Reference Voltage – E+ output adjustable from 2.4 V to 4.0 V Screw Terminal Blocks – Four terminals (E−, E+, A−, A+) for easy sensor wiring I2C Interface – Fixed address; use a multiplexer for multiple sensors on one bus STEMMA QT / Qwiic Connectors – Solderless I2C connection (cable not included) Typical Wiring E− → Ground (often black wire) E+ → Excitation voltage (often red wire) A− → Differential output − (often white wire) A+ → Differential output + (often green wire) Ideal For Digital scales and weight measurement Strain gauge and load cell applications Force and pressure sensing Industrial and scientific measurement projects Package Contents 1× Adafruit NAU7802 24-Bit ADC Breakout 4× Screw terminal blocks Resources Arduino Library (GitHub) CircuitPython Library (GitHub) Working with Multiple I2C Devices
