24-bit ADC module for strain gauge beams - HX711 - Adafruit 5974
Adafruit module with a precise 24-bit ADC converter , ideal for supporting strain gauges and Wheatstone bridges. Equipped with selective amplification (channels A: 64x / 128x, channel B: 32x) and the ability to connect two 4-wire sensors . Supports two data rate modes (10 SPS and 80 SPS), offering low power consumption (< 1.5 mA). Thanks to easy integration with microcontrollers via a pseudo-SPI interface and compatibility with CircuitPython and Arduino libraries, it is an excellent choice for measuring force or mass.

Product description: 24-bit ADC module for load cells - HX711 - Adafruit 5974
The Adafruit HX711 is a versatile and precise 24-bit ADC module designed to work with strain gauges and Wheatstone bridges . It allows you to connect two 4-wire sensors using a screw-type connector (channels A and B). Channel A offers a choice of 64x or 128x gain, while channel B has a fixed 32x gain. It supports two data rate modes: 10 SPS for accurate measurements and 80 SPS for fast readings. The module can be powered from 2.6V to 5.5V , and the built-in digital voltage regulator allows for the separation of analog and digital power supplies. Compatible with CircuitPython and Arduino , it offers intuitive setup and operation. Ideal for precision measurement applications such as electronic scales or force sensors.

Programming the board using CircuitPython and Python
The Adafruit HX711 supports a pseudo-SPI interface, which allows you to use any two digital pins of the microcontroller to transmit data . With the Adafruit_CircuitPython_HX711 and Arduino libraries, you can easily configure the module and read the ADC values. In CircuitPython, an example configuration involves connecting the DATA and SCK pins, and then setting channel A or B for measurements. The module allows for seamless integration into measurement projects, offering intuitive operation even for novice users.
