Description

NAU7802 I2C Load Cell Amplifier Qwiic Bare PCB

Manufactured by DIYIPCB using the open hardware design from sparkfun/Qwiic_Scale. Original design by SparkFun Electronics. This is an independently manufactured bare PCB, not an official product of the original designer.

Design functions

I2C interface for bridge-type load cells using the NAU7802 measurement circuit.

Typical applications

Electronic scales, weighing platforms, force measurement and strain-gauge development.

Main chips and components in the design

NAU7802 load-cell ADC / analog front end, with Qwiic-compatible I2C connections.

These functions and components describe the assembled design. The bare PCB contains no electronic components and does not perform these functions on its own.

What you receive

One unpopulated PCB. US$2.00 per board.

The load cell, cable and controller are not included. The completed system requires zero and span calibration with the selected load cell. Specify connector and calibration requirements for PCBA.

Images are bare-board CAD previews generated from the selected source. Actual soldermask color and surface finish may differ.
