"Product Features Rugged aluminum construction with strain relief pre-attached strain relief. Accurately measure 0-5 kg (0-11 lbs) of strength. HX711 - The top of the line sensor amplifier mounted on the breakout board is paired perfectly with the load cell to provide fast, accurate force measurements. It measures small changes in the resistance of the strain gauges mounted on the load cell and passes these values directly to any microcontroller such as the Arduino or Raspberry Pi. Load Battery Specifications - Pre-installed 22 cm (8.5 in) wire. The dimensions are 12.7 mm high, 12.7 mm wide and 80 mm long (0.5 inch x 0.5 inch x 3.15 inches). 4 mounting holes, 15mm apart on each side. One double tapping M4 thread and the other double tapping M5 thread.
