Regulator control output (NC when not used) The description for each pin is given below. HX711 is a16 pin device.The chip is available in various packages choose one based on your requirement. The chip has integrated preamplifier specifically to handle these low voltages. These outputs are difficult to handle directly by controllers, so we can use HX711 IC which takes these voltage signals and provide standard digital values which can be used by a microcontroller. The load cells which usually measure weight provide voltage outputs in millivolts. The chip is specifically designed for weight scales applications. HX711 is an ADC chip with preamplifier included.
