This HX711-based test board module serves as a precision signal conditioner and analog-to-digital converter for strain gauge load cells. It digitizes the small millivolt-level signals from load cells with high resolution, enabling accurate weight and force measurement in industrial and prototyping environments. The module incorporates digital filtering to ensure stable readings under mechanical vibration or shock.
Designed for robust integration, the board features comprehensive electrical protection including reverse connection and transient voltage suppression. Its wide operating temperature range of -40°C to +70°C ensures reliable performance in harsh conditions. The on-board display and keypad facilitate field calibration, tare zeroing, and parameter adjustment without requiring external software.
