Description
Module with electret microphone elektretowymand 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 inputsof 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 containgoldpin strap, it can be purchased separately
- Module dimensions : 17 x 11 x 8 mm
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 inputsof the Arduino) usingwiresor using breadboard. Pins are the solder fields, for soldering the goldpin connectors(2.54 mm pitch).
