M5Stack Mini Weight Unit HX711 Weighing Sensor

This Weight Unit features a 24-bit A/D chip HX711 weighing sensor designed specifically for electronic scales. The input multiplexer selects either Channel A or B as differential input for the low-noise programmable amplifier circuit. Channel A can be programmed with a gain of 128 or 64, which corresponds to a differential input voltage of ±20mV or ±40mV, when a 5V power 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.
