24-Bit HX711 Load-Cell Interface with Programmable Gain and Grove Connectivity

The M5Stack U030 Unit Weight is a compact load-cell signal-acquisition module based on the HX711 24-bit analogue-to-digital converter. Designed for electronic weighing applications, it amplifies low-level differential signals from an external strain gauge or load cell and converts them into digital measurement data that can be read directly by a compatible microcontroller through dedicated clock and data pins.

The module uses HX711 Channel A with programmable gains of 64 or 128, corresponding to full-scale differential input ranges of approximately ±40 mV and ±20 mV, respectively. It provides a 10 SPS output data rate and requires no internal register programming, simplifying integration into miniature weighing scales, kitchen scales, industrial measurement systems, logistics equipment, and laboratory weighing applications. The final measurement range and accuracy depend on the connected load cell, mechanical design, calibration, and controller implementation.
