From Makers Electronics's description

HX711 – Weighing Scale Analog-to-Digital Converter 24-bit The Load Cell Amplifier and ADC (Analog-to-Digital Converter) Module is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the module to your microcontroller you will be able to read the changes in the resistance of the load cell and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control, or simple presence detection. The HX711 uses a two wire interface (Clock and Data) for communication. Any microcontroller’s GPIO pins should work and numerous libraries have been written making it easy to read data from the HX711. The module communicates with the host computer through TTL 232. Features: Two selectable differential input channels Recommended excitation voltage: 5-10V. On-chip active low noise PGA with selectable gain of 32, 64 and 128 On-chip power supply regulator for load-cell and ADC analog power supply On-chip oscillator requiring no external component with optional external crystal On-chip power-on-reset Simple digital control and serial interface: pin-driven controls, no programming needed Measurement Resolution: 24 bit Specification Specification Value Differential Input Voltage ±40 mV (Full-scale) ADC Resolution 24-bit Refresh Frequency 80 Hz Operating Voltage 2.6 V – 5.5 V DC (5V) Supply Voltage Range 2.7 V – 5.5 V Operating Current < 10 mA Output Data Rate Selectable 10 SPS or 80 SPS Power Supply Rejection Simultaneous 50 Hz and 60 Hz rejection Operating Temperature -40°C to +85°C Pin Count 10 Pins Module Dimensions 34 × 21 mm Note: The module comes from the factory set to 10 SPS to ensure stable readings and minimize noise. Converting to 80 SPS requires expertise in precision soldering to cut the ground trace for the RATE pin and connect it to the high voltage (Logic HIGH). Pinout: Pin Description E+ Positive excitation output for the load cell. E- Negative excitation output for the load cell. A+ Positive input of Channel A (high-gain differential input). A- Negative input of Channel A. B+ Positive input of Channel B. B- Negative input of Channel B. VCC Power supply input (2.7V–5.5V DC). GND Ground (0V) power connection. DT (DOUT) Serial data output pin for communication with the microcontroller. SCK Serial clock input used to read data and configure the module. Packages Included: 1x HX711 – Weighing Scale Analog-to-Digital Converter 24-bit. 1x Pin Header. Documents: HX711 Datasheet.
