    Hello, is there, somewhere, a real complete diagram of this project? This subject is interesting but not clearly documented ... It's a shame! Thank you.

      Hi, pin A+ and pin B+ are connected together, on the same terminal block?

        @mfalkvidd If you have something related to this project, can you share it? (circuit schema or something)

            Hello, I will try to work again on this project in the coming days, I have made one years ago but reused (then broke !) the screen so it's not fonctional now. I will use another screen and make a functional one again as I will need it for some project.

                @Nca78 , my HX711 board looks like yours. I'm a bit confused on how to connect the J1 pins to the load / power. Can you share how did you connected it? Thx!

                Soldering is a bit messy and not helping much to understand, so I did a (gorgeous) drawing. I think I'll frame that in my living room :D

                And in case you want to increase the data rate

                  Is the result we get ac or dc?

                    @rvendrame sure, I'll do it tomorrow morning as I cannot do it right now. In case I forget, don't hesitate to ring me ;)

                    Hi to all,

                    These two resistors are 1K ? (betwen E+ and A+) and (E- and B+) ?
                    Need I use Diodes to ground ?

                      There a way you may have a chance to correct me, I have ordered everything I will need to build this project. I need your help to make a Scheme and how to wire part and connect the load, I have to 2 days trying to figuring out but I yet I need to understand it. You are the last user who visited the project. Thank you in advance if you are able to.

                        @mfalkvidd HI, There's a way you may help to do a circuit schema I am studying it, but yet I need to understand many thing how to wire it. If are able to. Thanks.

                          @EdCali sorry I don’t understand. I don’t know how this device is designed.
