Unit Mini Scales is an integrated mini weighing unit that incorporates a 5 Kg load cell, an ADC acquisition chip HX711, and a protocol conversion MCU, allowing direct output of weighing results. The product is equipped with an STM32F030F4P6 microcontroller, uses the I2C communication protocol for external communication, and supports multiple modules working together simultaneously. Additionally, it features an SK6812 RGB programmable LED indicator and a functional button, enabling users to easily perform zero calibration and tare adjustment. The top of the product is designed with M3 nut fixing holes, providing more installation options. Unit Mini Scales is suitable for scientific experiments, industrial production, and other fields.
