Featuring a frequency response of 20Hz to 20kHz and adjustable gain from 25x to 125x, it delivers clean, rail-to-rail 5Vpp output. This dual-pack includes fully assembled, tested boards with onboard electret microphones, perfect for voice changers, audio sampling, and reactive sound projects. ## Description Description: On the back, we include a small t pot to adjust the n. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp! You can set the n from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. Using introduction: Connect GND to ground, VCC to 2.4-5VDC. The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier (such as 3.7W stereo amp) If you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin directly to the microcontroller ADC pin. For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies. Package Included: 2pcs NOYITO MAX4466 Electret Microphone Amplifier ## Features - Add an ear to your project with this well designed electret microphone amplifier. This fully assembled and tested board comes with a 20 20KHz electret microphone soldered on. - For the amplification, we use the MAX4466, an op amp specifically designed for this delicate task The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried - This breakout is best used for projects such as voice changers, audio recording/sampling, and audio reactive projects that use FFT. - On the back, we include a small t pot to adjust the n. You can set the n from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6 " away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail to rail so if the sounds gets loud, the output can go up to 5Vpp - Using it is simple: connect GND to ground, VCC to 2.4 5VDC. For the best performance, use the "quietest " supply available (on an Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07HFSRGSG | | Brand | NOYITO | | Color | Purple | | Compatible Devices | Speaker | | Connector Type | Auxiliary | | Customer Reviews | 4.4 4.4 out of 5 stars (4) | | Input Voltage | 5 Volts | | Item Dimensions | 15 x 11 x 5 millimeters | | Item Weight | 10 Grams | | Manufacturer | NOYITO | | Mfr Part Number | MAX4466 | | Model Number | NOMAX4466 | | Number of Items | 2 | | Number of Ports | 2 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Amplifier,Microphone | | UPC | 680613660978 | | Unit Count | 1.0 Count | ## Product Details - **Colour:** Purple - **Compatible devices:** Speaker - **Connector type:** Auxiliary - **Item dimensions L x W x H:** 15 x 11 x 5 millimeters - **Specific uses for product:** Amplifier,Microphone ## Images ![NOYITO MAX4466 Electret Microphone Amplifier Adjustable Gain for Arduino - 2Pcs - Image 1](https://m.media-amazon.com/images/I/71FlZWlA58L.jpg) ![NOYITO MAX4466 Electret Microphone Amplifier Adjustable Gain for Arduino - 2Pcs - Image 2](https://m.media-amazon.com/images/I/71HcH2h9J4L.jpg) ![NOYITO MAX4466 Electret Microphone Amplifier Adjustable Gain for Arduino - 2Pcs - Image 3](https://m.media-amazon.com/images/I/61WrtH0uQML.jpg) ![NOYITO MAX4466 Electret Microphone Amplifier Adjustable Gain for Arduino - 2Pcs - Image 4](https://m.media-amazon.com/images/I/61g+8jJGmKL.jpg) ## Frequently Bought Together - NOYITO MAX4466 Electret Microphone Amplifier Adjustable Gain (Pack of 2) - uxcell a15080600ux0275 Metal Shell Round Internal Magnet Speaker 2W 8 Ohm (Pack of 4) - HiLetgo 5pcs LM386 Mono Audio Amplifier Module 200 Times AMP Solo 5V-12V 10K Adjustable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/322058992-noyito-max4466-electret-microphone-amplifier-adjustable-gain-for-arduino-2pcs](https://www.desertcart.is/products/322058992-noyito-max4466-electret-microphone-amplifier-adjustable-gain-for-arduino-2pcs) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-07-21*
