M5Stack Mini Weight Unit Load Cell Amplifier

This Weight Unit features a 24-bit A/D chip HX711 load sensor, specifically designed for electronic scales. The input multiplexer selects either channel A or B as the differential input for the low-noise programmable amplifier circuit. Channel A can be programmed with a gain of 128 or 64, corresponding to a differential input voltage of ±20 mV or ±40 mV when a 5V supply is connected. Channel B has a fixed gain of 32. No programming is required for the internal registers. Connect this Weight Unit to the GROVE PORTA on the M5Core or M5Stick.
