Description

Unit Mini Scales is an integrated mini weighing unit that incorporates a load cell with a capacity of 5 kg, an HX711 ADC acquisition chip, and a protocol conversion MCU, capable of directly outputting weighing results. The product is equipped with an STM32F030F4P6 microcontroller and uses the I2C communication protocol to communicate externally, supporting multiple modules working simultaneously. Additionally, it features an SK6812 RGB programmable LED indicator and a function button, allowing users to easily perform zero calibration and tare adjustment. The top of the product has reserved M3 nut mounting holes, offering more installation options. Unit Mini Scales is suitable for applications such as scientific experiments and industrial production.

    Okay, but with some limitations

    I don't really understand the choice of putting a button behind an I2C chip - this means no interrupt available, and makes working with that button quite awkward at best.

    In terms of the load cell itself - my unit had a significant amount of drift initially. We're talking over 40g over the course of an hour - basically forcing to go through the calibration process every time I wanted to take a measurement, which isn't exactly amazing. Since then, I took the unit apart and found an explanation - the upper part was pretty loose to the load cell itself, and tightening this screw made the drift much, much lower (it's still drifting by a few grams, but 1% accuracy on a 5kg load cell this cheap isn't too bad).

    The enclosure itself is a bit odd - two of the four mounting points are seemingly blocked by its upper half. Two is enough in my use-case, so that's fine, but definitely a bit odd.

    Overall, the idea of providing some logic over I2C to compute the weight is pretty good and well implemented, but I feel like going for M5Stack's Unit-Weight I2C and your own load cell and mounting/casing would be a better option - it seems to be everything that's good about this Mini Scales Unit, without the odd parts.

    Nicely built unit

    A very nicely constructed unit.
    Very easy to operate with the Core2 using Blocky!
