M5Stack Mini Scales Unit (HX711) - 5kg Load Cell, I2C Interface, STM32 MCU
The M5Stack Mini Scales Unit is a compact, integrated weighing module featuring a 5kg strain gauge load cell, HX711 ADC, and an STM32F030F4P6 MCU for direct digital output via I2C. It is designed for easy integration with Arduino, Raspberry Pi, ESP32, and other 3.3V/5V logic systems for precise force measurement applications.
Features
- Integrated 5kg strain gauge load cell with HX711 24-bit ADC for high-resolution weight measurement.
- STM32F030F4P6 ARM Cortex-M0 MCU handles signal conditioning and provides direct I2C digital output (Address: 0x26).
- Onboard SK6812 RGB LED and function button for visual feedback, zero calibration, and tare adjustment.
- Supports multiple units on a single I2C bus for scalable multi-channel weighing systems.
- Includes M3 mounting nuts and a 20cm HY2.0-4P cable for quick installation and prototyping.

The Mini Scales Unit is a complete weighing solution that integrates a precision strain gauge load cell, a high-resolution HX711 analog-to-digital converter, and a protocol-converting STM32 microcontroller. The load cell operates on the principle of a Wheatstone bridge, where applied force causes a change in resistance, which the HX711 amplifies and digitizes with 24-bit resolution.
The STM32F030F4P6 MCU manages the HX711, performs necessary filtering and calibration routines, and outputs stable weight data via a standard I2C interface. This design eliminates the need for external ADC circuitry and complex signal conditioning, providing a plug-and-play digital sensor module. The unit is housed in a robust casing suitable for benchtop and light industrial environments.
