Description

WEIGHT integrates a HX711 24 bits A/D chip that is specifically designed for electronic weighing device.

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 ±20mV or ±40mV respectively.

when a 5V supply is connected to AVDD analog power supply pin.

Channel B has a fixed gain of 32. There is no programming needed for the internal registers. All controls to the HX711 are through the pins.

In the test, we have this Unit channel A to connect a pressure sensor. Then, use M5Core screen to display the weight data.
