Featuring a PCM5102A chip with I2S interface support, pre-soldered stereo output, and compact PCB mounting, this dual-pack module delivers superior stereo sound for custom audio projects, smart speakers, and A/V applications. ## Description Description: DAC modules provide the Raspberry Pi with high quality DAC at an ultra-affordable price. Digital audio so it sounds far better than onboard analog audio. Stereo jack is already soldered to the board. Features: Line-Out Stereo Jack pHAT Format Board Use PCM5102A DAC to work with Raspberry Pi I2S interface. Specifications: Type: I2S DAC Decoder Model: PCM5102 Application: A/V Receiver DVD, BD Player HDTV Receiver Application requires 2VRMS audio output. Package Includes: 2 x I2S PCM5102 DAC Decoder Review: Works well when mounted close to the microcontroller. Must be configured for us. - Very good analog output sound quality using an I2S serial digital input. Uses Arduino Audio.h library. These devices must be configured before use. There are four jumpers on the back, each one must be configured for your application. Some boards come pre-configured for the most standard use case. There is also a small confuguration jumper on the front of the board. For most applications (3 wire) this configuration should be shorted. You can also configure the module from edge connectors. Lessons learned: I could not get the part to work even after 2 days. The module was configured properly, but wouldn't work. All wave forms were correct. The problem is the part needs to be fairly tightly coupled to the micro controller (Teensy 4.0) with a good ground. I was using standard hobbiest jumper wires over about 6" and I couldn't get it to work. I changed the configuration, mounting the Teensy and the 5102 on the same board, with less than 2" of separaton, and it worked first time. Not sure exactly why it didn't initially worked, as the waveforms lookekd good. Review: a creator's dream at this price - Works like a charm! Easy 5 stars for both price and usability. I use these DACs to build my own smart speaker for Home Assistant, and they've been fantastic. The only issue I ran into was a static hiss when the speaker was active, but twisting the L, R, and ground wires together while connecting the DAC to the amp solved it completely. Quick fix, no drama. Honestly, these cheap chips are a creator's dream. The only limit on what you can build is your imagination. And maybe the sound of Dad's voice saying, "That'll never work. Ambitious plan, but you need to be realistic." How wrong Dad was. So, 5 stars all day. Dirt cheap, dead simple to use, and the one minor quirk has an easy fix. If you're tinkering with Raspberry Pi or Arduino audio projects, grab a pair and start building. ## Features - DAC modules provide the Raspberry Pi with high quality DAC at an ultra-affordable price - Use PCM5102A DAC to work with Raspberry Pi I2S interface - IIS PCM5102 PCM5102A AUX Stereo Digital Audio - I2S DAC Decoder Board Module Voice Module Player Module Digital-Analog Converter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DNW32Y46 | | Brand | GODIYMODULES | | Brand Name | GODIYMODULES | | Customer Reviews | 4.8 out of 5 stars 22 Reviews | | Included Components | 2 | | Interface | I2C, I2S | | Interface type | I2C, I2S | | Manufacturer | GODIYMODULES | | Mounting Type | PCB Mount | | Mounting type | PCB Mount | | Number of Channels | 2 | | Number of Pins | 10 | | Number of channels | 2 | | Number of pins | 10 | | Part Number | GY-PCM5102-002 | | Unit Count | 2.0 Count | | Unit count | 2.0 Count | ## Product Details - **Brand:** GODIYMODULES - **Interface Type:** I2C, I2S - **Mounting Type:** PCB Mount - **Number of Channels:** 2 - **Number of Pins:** 10 ## Images ![IIS PCM5102 PCM5102A AUX Stereo Digital Audio I2S DAC Decoder Board Module Voice Module Player Module Digital to Analog Audio Converter for Raspberry Pi Arduino 2pcs - Image 1](https://m.media-amazon.com/images/I/71lpr6kcCAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well when mounted close to the microcontroller.

But test it on a solderless breadboard. DO pay attention to the reviews that tell you to configure the hardware jumpers. This is a necessary step. You will probably not get usable output with the stock settings. The biggest drawbacks: -- The Dupont wires are poor, and don't work reliably. -- The two rows of pin junctions are completely unaligned. The board will not plug into a standard perfboard with a 2.54mm pitch. IF you want both pin rows you must make a custom board. I'd use a different module if it's a permanent project setup. For testing or experimentation they work well. --- ## 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.hk/products/806191472-iis-pcm5102-pcm5102a-aux-stereo-digital-audio-i2s-dac-decoder](https://www.desertcart.hk/products/806191472-iis-pcm5102-pcm5102a-aux-stereo-digital-audio-i2s-dac-decoder) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-05*
