The ​Electronic Scale Motherboard PCBA is a precision-engineered printed circuit board assembly designed to power commercial, industrial, and medical weighing systems. It integrates a ​high-resolution ADC (up to 24-bit) and ​low-power MCUs (e.g., ARM Cortex-M4) to achieve measurement resolutions as fine as ​0.01g, ensuring compliance with ​OIML R76 and ​NTEP accuracy standards. Key features include auto-tare calibration, multi-sensor compatibility (strain gauges, load cells), and IoT-ready connectivity via ​Bluetooth 5.0 or ​Wi-Fi for real-time data logging. Built on ​RoHS-compliant FR4 substrates with ENIG surface finish, these PCBAs resist humidity and temperature fluctuations (-10°C to +50°C), making them ideal for retail scales, laboratory balances, and industrial weighing systems. Advanced models support touchscreen interfaces and cloud integration, aligning with smart manufacturing and Industry 4.0 trends.
