Unit Mini Scales
SKU:U177
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.
