I'm using two speakers, each will has its own lm386 amplifier and 9volt battery. They are fed PWM audio output from a microcontroller. The lm386 breakout was purchased from desertcart, they were a bit over a buck each. As another reviewer said, you probably couldn't buy the components that cheap. I 'fried' the one pictured by accidentally touching the positive lead from the battery to the ground on the breakout. Be careful about polarity on this one, they are not forgiving. I considered trying to replace the SOIC lm386-1 chip on the one I fried, but I doubt I could get a replacement chip for less than the price of a whole new board. I didn't understand the reason for the two ground pins at first, thought it was silly. Until I realized that I was the silly (ignorant) one. The two ground pins very conveniently allow you to connect the ground planes from the power source and the audio source. They are actually pretty much essential. There is a bright LED on each board, I carefully scraped it off to save power. With the LED the lm386 was drawing about 9.7 milliamps when idle. With it removed that dropped off to 1.2 milliamps. That should be significant for life of a 9 volt battery. I prior had salvaged the speakers from an old itunes docking station. Recycling them here, they are working very well with the lm386. The output from the lm386 is just right as it is set and plenty loud (and still clear) from the speakers. Review: small size, easy to use and connect - exactly as pictured, excellent product, it would have cost me more to build lm386 amp then the module cost, excellent value and fast delivery Would recommend this supplier. 5 stars ## Features - 🌟Product Name : Audio Amplifier Module;Chip : LM386 - 🌟PCB Board Size : 41 x 14mm(L*W);Material : Electric Part - 🌟Onboard LM386 Chip.With 200 multiplier benefits circuit design - 🌟On-board speaker wire holder - 🌟On-board 10K variable resistor, you can adjust the Amplification volume ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P38H4P8 | | Best Sellers Rank | #168,610 in Electronics ( See Top 100 in Electronics ) #1,044 in Audio Component Amplifiers | | Brand | Onyehn | | Date First Available | February 22, 2019 | | Item Weight | 1.76 ounces | | Item model number | LM386 | | Manufacturer | Onyehn | | Material | Electric Part | | Maximum Supply Voltage | 12 Volts (DC) | | Minimum Supply Voltage | 5 Volts (DC) | | Mounting Type | Through-Hole Mount | | Number of Channels | 1 | | Output Power | 0.25 Watts | | Package Dimensions | 7.17 x 5.47 x 1.38 inches | | Package Type Name | multi-item bag or bulk packaging | | Voltage | 12 Volts | ## Product Details - **Manufacturer:** Onyehn - **Maximum Supply Voltage:** 12 Volts (DC) - **Minimum Supply Voltage:** 5 Volts (DC) - **Mounting Type:** Through-Hole Mount - **Voltage:** 12 Volts ## Images ![10pcs LM386 200 Times gain Audio Power Module for Arduino EK1236 (Amplifier Board Mono Power Amplifier 5V-12V 10K Adjustable) - Image 1](https://m.media-amazon.com/images/I/81WLnPW6XUL.jpg) ## Questions & Answers **Q: What's the voltage across the potentiometer? could i replace it with a digital pot with max current 25ma (mcp4131-10kohm)?** A: Yes and no, if youre attempting to control the digital pot with an arduino to control volume, tbe answer is, 25ma is not enough current to drivw the high side. It would be better to add an additional digital pot to the input side. There its gonna depend on the voltage, id you're running it at 12v 25ma might be enough, but I dont think so. You'll need to know the output of whatever youre amplifying. **Q: can this be used as a headphone amp?** A: and, this is a mono (one channel) amp. . .for stereo you will nee two **Q: will this work well for a 1920's style crystal and one tube radio amplifier?** A: Absolutely! I am using one on my Poldhu 5 band radio that uses a 6al5 tube or diode (Crystal) for a detector. For a tube amp put a load resistor some kid of a transformer across the output and take the audio off across the resistor or the output of the transformer. Also using one on just a simple crystal set. Works great. **Q: How many output watts?** A: Only about 1W - but remember that this amplifier wants line-level input, which is very low power. Anything higher and this amplifier will distort beyond all recognition. :) If you want to amplify something like an output pin from an Arduino, use a PAM8403-based amplifier, that will do a great job up to about 3W. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These were great, easy to use *by D***L on October 25, 2021* I used them in a Halloween prop project.

Don't know why. Had some ICs on hand and replaced them. Working OK now. I use these on Crystal Sets I build for kids. Gives good volume with a four inch speaker. Worth the price. This is the first time I've hand any of these fail. ## Frequently Bought Together - Onyehn 10pcs LM386 200 Times gain Audio Power Amplifier Module for Arduino EK1236 (Amplifier Board Mono Power Amplifier 5V-12V 10K Adjustable) - HiLetgo 5pcs Micro SD TF Card Adater Reader Module 6Pin SPI Interface Driver Module with chip Level Conversion for Arduino UNO R3 MEGA 2560 Due - EDGELEC 120pcs Breadboard Jumper Wires 10cm 15cm 20cm 30cm 40cm 50 cm 100cm Wire Length Optional Dupont Cable Assorted Kit Male to Female Male to Male Female to Female Multicolored Ribbon Cables --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/122814721-10pcs-lm386-200-times-gain-audio-power-module-for-arduino](https://www.desertcart.com.kw/products/122814721-10pcs-lm386-200-times-gain-audio-power-module-for-arduino) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
