Description
Product information "SparkFun Load Cell Amplifier / Load Cell Amplifier, HX711"
This version of the SparkFun load cell amplifier has some changes that you specifically asked for! We've separated the analogue and digital supplies, and added a 3.3uH inductor and a 0.1uF filter capacitor for the digital supply. Need more? Take a look at the SparkFun Qwiic Scale. It has all the features of the HX711, but with added library support, a true I2C interface and no soldering required!
The HX711 uses a two-wire interface (clock and data) for communication. The GPIO pins of any microcontroller should work, and numerous libraries have been written to make it easy to read data from the HX711. See the connection guide below for more information.
Load cells use a four-wire Wheatstone bridge configuration to connect to the HX711. These are typically coloured RED, BLK, WHT, GRN and YLW. Each colour corresponds to the conventional colour coding of load cells:
- Red (excitation+ or VCC)
- Black (excitation or GND)
- White (amplifier-, signal- or output-)
- Green (A+, S+ or O+)
- Yellow (shielding)
Note: Special thanks to Bodge for providing the library for the HX711!
