## Description

Find setting up an amplifier IC on the breadboard a troublesome and totally no-need-to-repeat job? This Grove module can save you clutter to settle up such an IC by integrating the whole operating circuit. It's designed for precise differential-input amplification. Input the differential signals of your sensor to this module through the male pins, then your Arduino will get a precisely amplified output from the Grove interface. The gain scale factor is selectable. You can get a 35 times or 1085 times amplification via a switch on the board

**Features**

- High amplifying precision
- Selectable scale factor
- Can be conveniently read by Arduino
- Strong input protection: ±40V

**Application Ideas**

- Sensor signal amplifier
- Signal comparison
- General purpose amplification

For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
