Review: Easy to use with existing Arduino libraries - Purchased this to create a model rocket motor test stand. Used with Arduino UNO, microSD card, and 20kg load cell. Worked well, however, be aware this is not an I2C device. It doesn't make any claim that it is, but if you have any questions consult the HX711 datasheet.
Review: Works great! - The Sparkfun folks did a great job providing documentation that made connecting the load cell and HX711 amp to my Arduino. The library support is also excellent.

## Features

- HX711 IC: Weight items accurately; Note: Some calibration required
- Separated analog and digital supply: VCC analog voltage to power the load cell; VDD digital supply voltage used to set the logic level
- Two-wire interface (Clock and Data): communication with a microcontroller GPIO pins; Numerous libraries written: for easy-to-read data from the HX711
- Operation Voltage: 2.7V--5V: Allows wide range of microcontroller compatibility; Operation Current: < 1.5mA
- Connect using Wheatstone bridge configuration: Mostly standard Four-wire connection to load cells; Selectable 10SPS or 80SPS output data rate; Simultaneous 50 and 60Hz supply rejection

The Sparkfun folks did a great job providing documentation that made connecting the load cell and HX711 amp to my Arduino. The library support is also excellent.

### ⭐ Does not work
*by S***N on September 2, 2023*

The cheaper ones from China works. I was hoping the Sparkfun one is better and more stable, but it does not even work.
