What it is
HX711 Pre-Soldered Large Load Cell Amplifier Module for Arduino is a large-format HX711 24-bit ADC board for reading load cells in scales, weight sensing, and force measurement projects. It is pre-soldered for quick integration with Arduino and other microcontrollers such as ESP32 or Raspberry Pi, and the board silkscreen plus the HX711 datasheet should be used for pinout and wiring details rather than assuming an I2C, SPI, or UART layout.
Pins
Refer to the silkscreen labels on the board/module and the listing photos for exact pin names. Confirm the load cell and controller pinout with the HX711 datasheet before wiring.
