Mini Weight Unit (HX711) Load Cell Amplifier

Overview:

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