BDD HX711 24 Bit Weighing Module Digital Display Load Cell Amplifier 5V

The BDD HX711 Intelligent Display and Amplifier Weighing Module is a compact weighing interface designed for electronic scales, load-cell systems, and Arduino-based measurement projects. It combines a high-resolution 24-bit HX711 amplifier and analogue-to-digital converter with an integrated digital display, allowing load-cell signals to be amplified, processed, calibrated, and displayed in a convenient standalone module.

The module supports digital calibration and practical weighing functions such as zero setting, tare/peeling, anti-shake processing, and parameter storage. Its non-volatile memory retains configuration parameters after power is removed, making it suitable for repeatable weighing installations and embedded measurement systems.

Functions

Digital Calibration

The module supports digital calibration to help configure the display according to the connected load-cell arrangement and known reference weights.

Zero Setting

The zero-setting function allows the system to establish a zero reference before weighing.

Tare or Peeling

The tare function allows the weight of a container or other unwanted load to be removed from the displayed measurement.

Anti-Shake Processing

Anti-shake processing helps reduce fluctuations and provides a more stable displayed reading during weighing.

Parameter Retention

Configuration parameters are stored in non-volatile memory, allowing the settings to remain saved even after the power supply has been disconnected.

Applications

The BDD HX711 Intelligent Display and Amplifier Module is suitable for:

• Electronic weighing scales
• Platform scales
• Load-cell weighing systems
• DIY digital scales
• Arduino and microcontroller projects
• Industrial measurement prototypes
• Force and pressure measurement systems
• Educational electronics projects
• Custom weighing instruments
• Embedded load-cell monitoring equipment

Installation and Usage

Connect the compatible load cells to the module according to the required weighing arrangement. The system is specified for use with four 350 load cells. Supply the module with a regulated 5V DC power source, then use the keypad to configure the zero point, tare function, calibration, and acquisition speed as required.

The selected acquisition speed should be chosen according to the application. A higher sampling rate may be useful for faster changes, while a lower rate may be preferable where stable display behaviour is more important.

Important Information

• The module requires a 5V DC power supply.
• Confirm load-cell wiring and compatibility before connection.
• The stated sensor configuration is four 350 load cells.
• Calibration should be performed using suitable known reference weights.
• The module is intended for electronic weighing and measurement projects.
• The supplied specifications do not state the maximum weighing capacity, accuracy, excitation voltage, wiring colour code, or supported load-cell dimensions.
