Unit Mini Scales
Description
Mini Scales Unit is an integrated mini weighing unit that combines a 5kg weighing sensor, an ADC acquisition chip (HX711), and a protocol conversion MCU to directly output weighing results. The product is equipped with an STM32F030F4P6 microcontroller, uses the I2C communication protocol for external communication, and supports multiple modules working together.
Additionally, it features an SK6812 RGB programmable LED indicator light and a function button, allowing users to easily perform zero calibration and tare adjustment. The product also provides additional installation options with a reserved M3 nut fixing hole on the top. Mini Scales Unit is suitable for various fields such as scientific experiments and industrial production, where precise weighing is required.
