The module is based on a NAU7802 system enabling the reading of data from a strain-gauge beam. By connecting the model to the microcontroller, you can read the change in resistance of the beam with a small calibration, it is possible to make accurate measurements of weight. The board was equipped with clamp connectors and Qwiic connectors. It communicates using the I2C interface. Works with a voltage of 3.3 V.

Specification:

  • Supply voltage: 3.3 V (NAU7802: from 2.7 V to 5.5 V)
  • ADC converter: dual-channel, 24-bit
