Using them with ESP32 and different size weight sensors. For better results use ferrite filter and connect VCC to 3.3 volts.

Getting some excellent, clear measurements from this chip. They're quite easy to set up. Plenty of online tutorials. Super exciting project!

Of the HX711 chips I have used, this one was by far the worst. Does not provide stable readings, making it difficult to calibrate. While I do recommend using the HX711 load cell amp, I do not recommend this one.
