Description
Allows you to easily read load cells to measure weight
Uses a two-wire interface (Clock and Data) for communication
Four-wire wheatstone bridge configuration to connect
Simultaneous 50 and 60Hz supply rejection
The HX711 Load Cell Amplifier is a small breakout board that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presence detection.
Works well. Raspberry PI + Pi4j code https://github.com/Poduzov/HX711-Pi4j

Surprisingly good
Wasn't expecting great accuracy, but easily got +/-3g resolution from 250kg load cell without any noise-reducing measures or tinkering. Admittedly the load cell cost 20x as much!

Good branded item
Since it's sparkfun branded, you can buy with confidence. Works as expected, very well, with 100g load cell from robotshop: RB-Phi-203. Well made board.
