Hi,i need to create a scale for a rocket motor test-stand and i have some questions:
-i planned to use a qwiic scale nau7802 connected to an esp32 via I2C, are the two things compatible?(will the library work?)
-i want to use loadcells that have a 5v excitation voltage,but i think the qwiic scale can only provide 3.3v,is it a problem If i use 5v external to power the loadcell and then i connect the other two wire remaining to the qwiic scale?
Thanks
The library was tested on a ATmega328 and not a ESP32, it's possible the library might need a bit of tweaking to run on the ESP. (You'd need to give it a try and see.) It will probably run just fine but just be aware there could be some bugs running it on a ESP.use a qwiic scale nau7802 connected to an esp32 via I2C, are the two things compatible?
Not a problem. Load cells are just precision variable resistors, they won't care if the voltage is a bit less than 5 volts.i want to use loadcells that have a 5v excitation voltage,but i think the qwiic scale can only provide 3.3v
