Product description: Module for strain gauge beams - with ADC 24-bit converter NAU7802 - STEMMA QT / Qwiic - Adafruit 4538
The Adafruit module is equipped with the NAU7802 chip, which enables reading data from strain gauge beams . Includes ultra high resolution 24 bit differential ADC with additional gain and calibration circuits. After connecting the module to the microcontroller board, you can read the change in beam resistance , and after calibration, you can accurately measure the balance. The board has been equipped with Qwiic connectors, fields for soldering screw joints and outputs in the form of solder pads to the doldpin strip.
The product is compatible with Raspberry Pi and Arduino!
