Description

Module with electret microphone elektretowym and operational amplifier. Thanks to the applied system amp (OPA344), the voltage signal of the microphone is amplified 100-times. This allows for the direct connection of the module to the input pins of the analog-to-digital converter (e.g. analog inputs of the Arduino). The system is powered with the voltage ranging from 2.7 V to 5.5 V.

 

Specification

  • Supply voltage: from 2.7 V to 5.5 V
  • Current consumption: max 0.5 mA
  • Frequency range: 100 Hz to 10 000 Hz
  • The set does not contain goldpin strap, it can be purchased separately

  • Module dimensions : 17 x 11 x 8 mm

Connection method

Power should be connected between the pins of VCC (2.7 V to 5.5 V) and GND (ground). AUD is an output of amplified analog signal. It must be connected to the input pins of the analog-to-digital converter (e.g. analog inputs of the Arduino) using wires or using breadboard. Pins are the solder fields, for soldering the goldpin connectors (2.54 mm pitch).
