The SparkFun 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.

This version of the SparkFun Load Cell Amplifier features a few changes that you specifically asked for! We have separated the analog and digital supply, as well as added a 3.3uH inductor and a 0.1uF filter capacitor for digital supply.

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 configuration to connect to the HX711. These are commonly colored RED, BLK, WHT, GRN and YLW. Each color corresponds to the conventional color 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 color coding.

Note: Special thanks to Bodge for supplying the Library for the HX711!

Features:

  • Operation Voltage: 2.7V–5V
  • Operation Current: < 1.5mA
  • Selectable 10SPS or 80SPS output data rate
  • Simultaneous 50 and 60Hz supply rejection

A Tissue Box That Finally Understands the Assignment
Color: Retro
I tested this vintage-style tissue box cover with the same scrutiny I give freeze dryer liners and financial models—and it passed with charm and function. Material & Build: The PU leather has a raised floral relief that mimics carved wood surprisingly well. It’s backed by MDF and lined with non-woven fabric, which makes it both sturdy and easy to wipe clean. I spilled coffee on it (not intentionally), and it didn’t flinch. Functionality: It fits a standard rectangular tissue box and—bless it—completely hides the garish branding and neon graphics that manufacturers seem to think belong in a living room. This cover restores dignity to the humble tissue. Design: It’s waterproof, durable, and doesn’t collapse when tugging out a tissue. The vintage look is intentional, not kitschy. Think “grandmillennial chic” rather than “forgotten attic find.” Accessibility Note: The texture and structure make it easy to locate and use for seniors or anyone with low vision. No sliding around or crushed corners. If you’ve ever looked at your tissue box and thought, “Why must you be like this?”—this cover is your redemption arc. It’s a small upgrade that quietly improves the space and makes you feel like your home is curated, not cluttered.

Love these.
Color: Gray
Never thought I'd "love" a tissue box holder but these are very nice. Weighted do the box doesn't move when you pull a tissue out. Bottom is magnetic, and they don't look cheap. Look well made. Highly recommend!

I like this.
Color: Black
Tissues are necessary sometimes, them funky designs on the boxes aren’t. A discreet way to keep the essentials on hand, and add a touch of class. Sturdy construction. Good rich color. Very easy to refill or remove.size fits Kleenex box perfectly. And the material feels lush.

Nice box but, needs tissue springs.
Color: Brown
These boxes are well made and elegant. I like the magnetic closure and the rear-filled design. The only thing is that you'll want to use some tissue dispenser springs underneath once the tissue is half gone so that the popup feed continues working. Putting springs in when fully loaded cannot be done because pulling out a tissue will rip them.
