Grove - Differential Amplifier

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.
