Review: Cheap, but nice! - Very cheap; but very useful. Nicely design!
Review:  Not functional. Might be knockoff chips  - The 1st photo shows a board with "MH" stamped on it. The actual chips they sent do not. They are different and look like the ones shown in photo 3. The boards are physically different. There is a lead from the HX711 "rate" to GND which is supposed to set the rate at 10 SPS per the data sheet. The HM chips don't have this (maybe imbedded, not sure). Other than that, I'm not sure the all the exact differences in the board. All I know is that they don't work. I bought a single board and 4 gage package from a different seller. It had a HM printed on the board. When hooked up to an Arduino, everything works fine. The chips reads (as well as the system can anyways) Since this one worked for my project, I ordered 2 sets of 2 each from this seller (so I could have a total of 5). figured I'd save a few buck getting them 2 at a time. They do NOT work. I tried everything including writing a bit-banging sketch to verify that it just wasn't incompatible with the HX771 library I was using. They don't work. The program hangs up after the first (erroneous) reading. I've tried 3 different HX711 libraries. I tried physically cutting the "rate" lead on the board (even though this should be correct per the HX711 data sheet). Nothing. The 4 boards from this seller do not read. The one with the MH does fine. There's something wrong with these. I don't know exactly what, but there is something wrong.  OK, so after pulling out my hair for more time than I wanted, I figured it out These boards are not wired properly. There is a pin for AGND on the HX711 chip that needs a ground. it's right there in the diagrams they have attached. instead, they just wired it to "-E". There's enough voltage bleed to totally screw up the circuit. This is bad design and incorrect. There is a solution... wire a jumper from -E all the way over to Ground. That got them working again. reading seem normal now. Although you shouldn't have to rewire a faulty design.

## Features

- This module uses 24 high precision A/D converter chip hx711, specially designed for the high precision electronic scale
- The load sensor is a group of half-bridge strain gauge, there are 3 ways to use it.
- Use one load sensor 50kg with an external resistor to form a full-bridge measurement, the range of a sensor range: 50kg. External resistance on the higher requirements.
- Use two weight sensor 50kg to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg
- Use four weight scale 50kg to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg

### ⭐⭐⭐⭐ a little fidgety but I got it working.
*by N***N on May 26, 2024*

I ran mine into a nodemcu. I found one of the amplifiers was dead but it may have been my fault, I initially hooked it into the 5v feed. I found a great tutorial on youtube that showed how to setup a whetstone bridge with the hx711 and that set me on the right path. The most challenging part which I didn't initially understand was to route out a board to set the sensors into so they were suspended properly in such a way to allow a reading. Initially I just hot glued them flat to a board and that doesn't work. I used a 1" forstener to make a 1/4" deep hole in a piece of plywood and then glued them in place. In the next iteration I'll go dig for 3d printed feet since I've seen reference above to that.
