This small breakout board kit is a load cell amplifier with HX711 chip, designed for high-precision electronic scales for 24-bit A/D, which can easily read the load cell to measure weight. This kit also includes the Load Sensing Combiner, which works great with our Load Cell Amplifier breakout board. By connecting the amplifier to your microcontroller you will be able to read the change in load cell resistance and with some calibration you will be able to get a very accurate weight measurement. We separate the analog and digital power and added a 3.3uH inductor and a 0.1uF filter capacitor for digital power. And the five pins on the edge of the combiner can line up directly with the five pins on the amplifier. The default output data rate is 80SPS, you can also choose 10SPS, and HX711 uses a two-wire interface (clock and data) to communicate. The load cells use a four-wire Wheatstone bridge configuration to connect to the HX711. These colors are usually red, black, white, GRN, YLW.
