Excellent Amplifier for Precise Weighing

After I put it to the test, the SparkFun Load Cell Amplifier proved to be a game changer for my scientific experiments. Its accuracy is unparalleled, and it's incredibly easy to use .The only downside is that it's a little expensive compared to other amplifiers..

Pros
  • Highly accurate, user-friendly
Cons
  • Expensive compared to other options.

worked fine for a few days and then died

Hello, I usually support SparkFun products, but in this case I advise caution.

I was right that it was more stable, but after a few days it just stopped working. I have no idea what happened to him because he was in a working system, untouched by human hands. Possibly a power surge I think, but none of the other components were affected. I…

Pros
  • Selectable baud rate 10 SPS or 80 SPS. Simultaneous 50 and 60 Hz power suppression
Cons
  • Slightly crumpled
