Mini Weight Unit (HX711) Load Cell Amplifier

Description

Unit Weight is a weighing unit. It integrates the 24-bit A/D converter chip HX711, which is specifically designed for high-precision electronic scales. This design utilizes only Channel A, amplifying the acquired signal through its built-in low-noise programmable gain amplifier (PGA). The programmable gain of Channel A can be set to 128 or 64, corresponding to full-scale differential input signal amplitudes of ±20mV or ±40mV, respectively. All control signals are driven by pins, eliminating the need to program the chip's internal registers. This product is suitable for high-precision weighing systems, industrial automation control, logistics and warehouse management, food processing, pharmaceutical measurement, and other fields.
