Description

• SparkFun Qwiic Scale Breakout Board
• Features a small breakout board for the NAU7802
• Allows to easily read load cells to accurately measure the weight of an object
• Able to read the changes in the resistance of a load cell
• Doesn’t need soldering to connect it to the rest of your system

The SparkFun Qwiic Scale Breakout Board – NAU7802 is a small breakout board for the NAU7802 that allows you to easily read load cells to accurately measure the weight of an object. By connecting the board to your microcontroller you will be able to read the changes in the resistance of a load cell and, with some calibration, you’ll be able to get very accurate weight measurements.

This can be handy for creating your own industrial scale, process control or simple presence detection. Utilizing the handy Qwiic system, no soldering is required to connect it to the rest of your system. However, 0.1″-spaced pins have been broken out in case you prefer to use a breadboard.
