Product description: Module for load cells - with 24-bit NAU7802 ADC - STEMMA QT / Qwiic - Adafruit 4538
This Adafruit module, equipped with the NAU7802 , allows for reading data from strain gauge beams . It includes a very high-resolution 24-bit differential ADC with additional gain and calibration circuitry. Connecting the module to a microcontroller board allows for reading the change in the beam's resistance , and after calibration, accurate weight measurement can be performed. The board is equipped with Qwiic connectors, soldered screw terminals, and solder pads for a doldpin header.
Product compatible with Raspberry Pi and Arduino!
