If you use 5 volt power, output levels, even from background noise, will be almost 5 volts, and any intended input will clip. Using 3.3 volts on Arduino or Pi will give you about a 2 volt floor that will eliminate most clipping. There is some slight noise in the output, so I am going to try 2.5 volt vcc. Great find. ### ⭐⭐⭐⭐ Works pretty well, but seems to eat batteries. *by H***R on May 20, 2025* I rigged the microphone up with an old amplifier and some earphones to facilitate conversation with my hearing impaired wife. The setup works really well, except that I powered the mike with a couple of AA batteries. Sadly the batteries don't last very long. I haven't measured the current drain yet, but it must be fairly hi, ### ⭐⭐⭐⭐⭐ Item received as expected. *by E***Y on October 20, 2023* Prompt service. I ordered these for a students project. Unfortunately I threw the package away and had to reorder. Second order arrived quickly. No issues with devices. Student has will install next week. ## Frequently Bought Together - HiLetgo 2pcs Electret Microphone Amplifier MAX4466 Module Adjustable Gain Blue Breakout Board for Arduino - Teyleten Robot ESP32S ESP32 ESP-WROOM-32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 3PCS) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## 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.es/products/69253104-hiletgo-2pcs-electret-microphone-amplifier-max4466-module-adjustable-gain-blue](https://www.desertcart.es/products/69253104-hiletgo-2pcs-electret-microphone-amplifier-max4466-module-adjustable-gain-blue) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-04-22*
