It connects via a 4-pin JST SH connector and supports a 1-3 MHz clock rate, making it ideal for modern 32-bit processors without analog inputs. With an onboard jumper to toggle left/right channel output, this breakout is perfect for makers seeking high-fidelity digital audio integration beyond traditional analog or I2S mics. ## Description An exotic new microphone has arrived in the Adafruit shop, a PDM MEMS Microphone! PDM is the 'third' kind of microphone you can integrate with electronics, apart from analog or I2S. These microphones are very commonly used in products, but are rarely seen in maker projects. Still, they have some benefits so we thought we'd offer a breakout for the shop. The first thing to note is that this sensor does not provide an 'analog' output like many of our electret microphone assemblies. So it's great for chips that do not have analog inputs. Secondly, the digital interface is a very simplistic pulse density modulation output. It's digital but its not PWM and it's not I2S. You will need to make sure your chip has a PDM interface - most 32-bit processors these days do! PDM is a little like 1-bit PWM. You clock the mic with a 1 MHz - 3 MHz clock rate, and on the data line you'll get a square wave out that syncs with the clock. The data line with be 0 or 1 logic output, with the square wave creating a density that when averaged will result in the analog value out. There's a few ways to manage these mics: Your chip comes with a hardware peripheral and library that does all the data managing at high speed, collects samples, applies a filter and gives you an analog value (The nRF52840 is like this and it is ideal!) Your chip comes with a hardware peripheral that gives you values, then it is up to you to perform the decimation/filtering. (We have some example code for this on the ATSAMD21 chipset) Your chip does not come with a hardware peripheral but you're pretty clever and come up with a way to make it work using SPI (See this example for the ATtiny85) You generate the high speed clock, then add an analog filter on the data line, and read the analog value (A hack, but works!) ## Features - Fully assembled and tested microphone - A 4-JST SH connector with 3V, GND, DAT, CLK connections - On-board solder jumper lets you change the mic from Left to Right channel - 1 MHz - 3 MHz clock rate - A microphone you can integrate with electronics, apart from analog or I2S ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Z496ZMK | | Antenna Location | Voice Recording, Video Recording, Video Conference, Singing, Karaoke | | Best Sellers Rank | #1,088,299 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #159 in Microphone Elements | | Brand | Adafruit | | Built-In Media | Microphone | | Compatible Devices | Smartphone, Laptop, Personal Computer | | Connectivity Technology | XLR | | Connector Type | JST SH | | Customer Reviews | 3.6 3.6 out of 5 stars (7) | | Enclosure Material | Copper | | Manufacturer | Adafruit | | Mfr Part Number | 4346 | | Microphone Form Factor | Mini | | Model Number | 4346 | | Number of Channels | 1 | | Polar Pattern | Unidirectional | | Power Source | Corded Electric | | Special Feature | PDM | ## Product Details - **Brand:** Adafruit - **Compatible Devices:** Smartphone, Laptop, Personal Computer - **Connectivity Technology:** XLR - **Connector Type:** JST SH - **Included Components:** Microphone - **Microphone Form Factor:** Mini - **Polar Pattern:** Unidirectional - **Power Source:** Corded Electric - **Recommended Uses For Product:** Voice Recording, Video Recording, Video Conference, Singing, Karaoke - **Special Feature:** PDM ## Images ![Adafruit 4346 PDM Microphone Breakout with JST SH Connector - Image 1](https://m.media-amazon.com/images/I/615xATLAZVL.jpg) --- ## 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.com.ar/products/191649539-adafruit-4346-pdm-microphone-breakout-with-jst-sh-connector](https://www.desertcart.com.ar/products/191649539-adafruit-4346-pdm-microphone-breakout-with-jst-sh-connector) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-20*
