Digital Load Cell Weight Sensor + HX711 Weighing Breakout Board AD Module Pressure Sensors for Arduino DIY Electronic Portable Kitchen Scale (1KG+HX711)

I connected it to an Arduino Nano Every and it works as expected. For software, use the Arduino HX711 library which takes care of reading the HX711. The sampling rate of the HX711 is determine by the clocks it uses. With its internal clock, it can sample 10 or 80 times a second but this board is hard wires for 10 samples/sec and doesn't have the jumper to set it to 80 times/sec. If you need the higher rate, get a different HX711 board, they are inexpensive, or lift pin 15 of the IC and short it to pin 16. You can go up to bout 140 samples/sec if you install a crystal as explained in the HX711 datasheet.

I was scared it was going to come damaged given the fragility of the product. But it came packaged well and intact and worked upon opening. Good product.

This works really well. It is only as good as the scale you have on hand to calibrate it. I have a 1kg scale that is .01 grams of resolution. With that calibration information, I got the load cell to be about .1 g precise. The values would fluctuate about .1 g. However, it takes 100ms to make this reading! A moderate downside if you are using Arduino. MCUs can have feedback loops running into the 100s of Hz. It is possible to request the reading, and then do something else while you wait for the response, but still the result will be delayed from reality. I know it is possible to change it to 80Hz... but really? Small SMD soldering? I don't think so.

The PCB is hardwired for 10hz, I had to cut the PCB trace and manually connect the RATE pin to 5v(adjacent pin) in order to get it working at 80hz. Overall works as expected.

VERY flimsy wires. They break extremely easily.

FYI: On the 1KG load cell, all 4 screws are M4 - 0.7.

Very stable if you tare it before each measure

Either the PCB is very low quality or the soldering was not done properly. There is intermitent resetting of the circuit... which made me waste countless hours debugging as I thought it was a bug in my code/hardware. But upon further testing (using 3 different Arduino boards, breadboard, cable assemblies, etc) I was able to pinpoint the issue to the Vcc input of the PCB.

Very great quality and precision.

The drawing provide for the size are of screw, and the distance between the each screw are all wrong
