Hello, I'm planning (or dreaming) to make 100g/1mg repeatability scale using Arduino and HX711. I ordered few modules and load cells from ebay, and started researching stuff. Reading datasheets I noticed that HX711 has 20mV full range ACD with 128 times gain, that means, ideally load cell should p…

HX711 with external excitation voltage

The common mode voltage, the average on the two inputs, will be 5 volts. NG.
