Industrial Weight scale

The industrial weighing scale is composed of NuMicro® M254 microcontroller and NADC24 analog-to-digital converter. NADC24 is a high-precision 24-bit ΔΣ analog-to-digital converter (ADC). It is primarily used to capture and process signals from load cells, utilizing its integrated programmable gain amplifier (PGA) and digital filter (FIR) to enhance accuracy and provide precise weight measurements. NuMicro® M254 microcontroller reads the value converted by NADC24 through the SPI interface. After calculation, it can display four different weight units, gram (g), kilogram (kg), pound (lb), and ounce (oz) on the segment LCD.
