Description M5Stack Weight I2C Unit is a compact load cell measurement module that combines an STM32 controller with the HX711 weight-sensing solution for precise digital weighing over I2C. With 24-bit weight measurement capability and straightforward bus communication, this HX711 weighing sensor is a practical option for compact scale systems, industrial weighing control, and smart scale projects. Features This unit uses an STM32 + HX711 solution for digital weight acquisition. This load cell measurement module supports 24-bit weight measurement accuracy. The HX711 weighing sensor communicates over I2C at address 0x26. Multiple devices can share the same I2C bus for broader collection layouts. It works well for industrial weighing control, data collection, and smart scale projects. Specifications Product Weight I2C Unit Core Solution STM32F030F4P6 + HX711 Resolution 24Bit Communication Mode I2C (0x26) Operating Temperature 0-40°C Product Size 32 × 24 × 11.3mm Package Size 136 × 92 × 13.7mm Product Weight 5.2g Package Weight 12.9g Applications This module is suitable for micro-gravimeter projects, smart scale projects, food processing systems, logistics platforms, and laboratory investigation workflows. Because this weighing interface gives stable digital output, it is also useful in industrial weighing control and embedded 24-bit weight measurement tasks where a small footprint matters.
