OpenScale - strain-gauge bridge ATmega328P - SparkFun SEN-13261

Module for measuring the weight and temperature. It is used to read data from the strain-gauge sensors. It allows for calibration, setting the sampling frequency and accuracy. It communicates via UART with the built-in miniUSB port. It works with voltage of 5 V.

The module has the following systems:

• Microcontroller ATmega 328P for addressing and data transfer
• FT231 with a miniUSB port and for serial transmission
• HX711: 24-bit A/D converter for measuring the weight
• TMP102 for registering the temperature of the environment

The product is compatible with Arduino

• The manufacturer provides a user guide along with a sample program for Arduino.

• Supply voltage: 5 V
• Consumption of the current: up to 100 mA
• The possibility of choosing the sampling rates: 10 sps to 80 sps
• Sensor of internal and external temperature
• Communication: UART from 1200 bps to 1000000 bps (by default is 9600 b/s)
• Pins:the miniUSB port, screw connections and holesfor goldpinconnectors - 2.54 mm(the strap can be purchased separately)
• Module dimensions: 55 x 47 mm
