2PCS Electret Microphone Amplifier Module MAX4466 Adjustable Gain 30dB Audio Preamp Board for Arduino

2PCS Electret Microphone Amplifier Module MAX4466 Adjustable Gain 30dB Audio Preamp Board for Arduino Description

Compact 30dB Gain Amplifier Module Key benefits Boosts weak analog signals by 30dB to improve detectability and measurement accuracy. Low voltage operation from DC 2.4V to 5.5V enables use with battery powered systems and common logic supplies. Very small PCB footprint at 16mm x 12mm for tight spaces and lightweight projects. Simple integration into existing circuits for signal conditioning without major redesign. Why you need it Raises lowlevel signals to usable levels for analog to digital conversion and downstream electronics. Reduces the need for complex external amplification stages, saving space and design time. Works with a wide range of small electronics where compact size and low supply voltage are critical. What makes it stand out Fixed 30dB gain provides predictable, repeatable amplification. Wide supply range supports singlecell and multicell battery setups and standard 3.3V or 5V systems. Compact PCB construction lets you place amplification close to the signal source to minimize noise pickup. Compatibility and performance Function: small signal amplifier module for use in audio, sensor, and general signal conditioning applications. Compatibility: suitable for microcontroller and single board computer projects, portable recorders, sensor front ends, and other low voltage electronics that accept DC 2.4V to 5.5V. Size and material: compact 16mm x 12mm printed circuit board for tight installation. Performance: fixed gain of 30dB for consistent amplification of small signals. Typical use scenarios Microphone preamplifier for portable voice or field recording projects where space and power are limited. Sensor signal conditioning to boost weak outputs before analog to digital conversion in microcontroller applications. Small audio and electronics prototypes that require a compact, low voltage amplifier to test or drive downstream stages. Technical specifications Gain: 30dB Working voltage: DC 2.4V to 5.5V Board size: 16mm x 12mm Construction: compact PCB module Notes Intended for general signal amplification and conditioning in electronic projects. Check input and output levels in your system to ensure compatibility.
