Its robust noise rejection and easy microcontroller integration make it a top choice for industrial and DIY scale projects. ## Description The Load Cell Amplifier is a small breakout board for the HX711 IC 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. The HX711 uses a two wire interface (Clock and Data) for communication. Any microcontroller’s GPIO pins should work and numerous libraries have been written making it easy to read data from the HX711. Check the hookup guide below for more information. Load cells use a four wire wheatstone bridge to connect to the HX711. These are commonly 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 : (Shield) The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI (electromagnetic interference). Please keep in mind that some load cells might have slight variations in colour coding. Review: Typical Sparkfun quality: excellent. - Works great. Documentation is excellent. Plenty of tutorials available to help with wiring and programming. Standard libraries available for Arduino. What more could you ask for? Review: This is the best HX711 board. - Get this one. It's worth the extra money over the cheap Chinese HX711 boards. I believe it has some extra noise filtering and it makes a real difference. ## Features - Operation Voltage: 2.7V-5V, Operation Current: < 1.5mA - Selectable 10SPS or 80SPS output data rate - Simultaneous 50 and 60Hz supply rejection - Model number: SEN-13879 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NPZ4CPG | | Best Sellers Rank | #168,438 in Electronics ( See Top 100 in Electronics ) #1,037 in Audio Component Amplifiers | | Brand | SparkFun | | Brand Name | SparkFun | | Color | Red | | Customer Reviews | 4.0 out of 5 stars 28 Reviews | | Global Trade Identification Number | 06955900326450 | | Item Dimensions | 1.18 x 0.91 x 0.2 inches | | Item Weight | 0.01 Kilograms | | Item dimensions L x W x H | 1.18 x 0.91 x 0.2 inches | | Manufacturer | Cool Components | | Maximum Operating Voltage | 5 Volts | | Measurement Type | weight | | Minimum Operating Voltage | 2.7 Volts | | Model | SEN-13879 | | Part Number | SEN-13879 | | Power Source | Battery Powered | | Specification Met | NIST | | Style | Compact | | Style Name | Compact | | UPC | 717520030058 602401874688 | ## Product Details - **Brand:** SparkFun - **Color:** Red - **Item Weight:** 0.01 Kilograms - **Power Source:** Battery Powered - **Style:** Compact ## Images ![SparkFun Load Cell Amplifier - HX711 - Image 1](https://m.media-amazon.com/images/I/61VizkyZc-S.jpg) ![SparkFun Load Cell Amplifier - HX711 - Image 2](https://m.media-amazon.com/images/I/51KoQUxT02L.jpg) ![SparkFun Load Cell Amplifier - HX711 - Image 3](https://m.media-amazon.com/images/I/51OP2Xo4DFL.jpg) ![SparkFun Load Cell Amplifier - HX711 - Image 4](https://m.media-amazon.com/images/I/51Y91cw2MML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Typical Sparkfun quality: excellent. *by C***Y on October 13, 2025* Works great.
