This HX711 Load Cell Amplifier Module allows you to easily read load cells to measure weight. This Load Cell Amplifier Module uses 24 high-precision A/D converter chips HX711. This module is specially designed for the high-precision electronic scale design, with two analog input channels, and the internal integration of 128 times the programmable gain amplifier. The input circuit can be configured to provide a bridge-type pressure bridge.
The HX711 uses a two-wire interface (Clock and Data) for communication. HX711 has added advantages such as high integration, fast response, and immunity. This is why any microcontroller's GPIO pins should work, and numerous libraries have been written, making it easy to read data from the HX711.
Note: This product comes with two different boards with different print and layouts on PCB but the functionality and operation are the same on all Boards
