Hello everybody,

I am using a Hx711 module to measure weight.

It is connected to the D7(Clock) and the D8(Data) pins of the nodeMCU.

I am using the nodemcu power supply for the Hx711 module.

If I want to upload the sketch to the nodeMCU I have to unplug the power of the Hx711. I would like to know what happen?

Another issue is that, after upload the sketch I power on the hx711 and all works fine, but if i reset the nodeMCU, it does not work.

I hope you can help me.

Thanks.

D8 is the GPIO15, which need to be pulled down at power up or reset.

Thanks martinayotte,

Which pins do you suggest for that connection?

Thanks.

If you didn't already used it, you can use GPIO4/GPIO5 for example (D2/D1).
