HX711 Load Cell Amplifier Module with 4-Digit Digital Display

This HX711 load cell amplifier module features an integrated four-digit digital display to provide clear weight readings up to 9999g. It connects to 5kg or 10kg load cell sensors and includes onboard calibration and tare functions that retain settings across power cycles. It is ideal for students, makers, and hobbyists building standalone digital weighing systems.

Integrated digital readout

The module features a 4-digit digital tube display capable of displaying measurements up to 9999g. When paired with a 5kg sensor, measurement accuracy typically fluctuates around 1g under stable power supply conditions.

Calibration and data retention

The board includes onboard functions for peeling and calibration upon first connection. Calibration parameters are automatically retained in memory after power-off, removing the need to recalibrate on subsequent uses.

Power and connectivity

Power can be supplied via a USB cable or through dedicated wiring connections over a DC 3V to 5.5V range. The board offers two selectable differential input channels, on-chip power-on-reset, and power-saving functionality.
