This Dual Channel HX711 Weighing Module is a precision 24-bit analog to digital converter (ADC) designed for weight scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input voltage of & plusmn;20mV or & plusmn;40mV respectively, when a 5V supply is connected to AVDD analog power supply pin. Channel B has a fixed gain of 32. On-chip power supply regulator eliminates the need for an external supply regulator to provide analog power for the ADC and the sensor. Clock input is flexible. It can be from an external clock source, a crystal, or the on-chip oscillator that does not require any external component. On-chip power-on-reset circuitry simplifies digital interface initialization.
There is no programming needed for the internal registers. All controls to the HX711 are through the pins

Item Description
This transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer & rsquo;s core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (E.M.F) or voltage in the secondary winding. The transformer has cores made of high permeability silicon steel. The steel has a permeability many times that of free space and the core thus serves to greatly reduce the magnetizing current and confine the flux to a path which closely couples the winding.
It is a general purpose chassis mounting mains transformer. Transformer has 240 V primary winding and center tapped secondary winding. The transformer has flying colored insulated connecting leads ( Approx 100 mm long ). The Transformer act as step down transformer reducing AC & ndash; 240V to AC & ndash; 12V
