Selected User Reviews For HiLetgo PCM5102 I2S IIS Lossless Digital Audio DAC Decoder Module Stereo DAC Digital-to-Analog Converter Voice Module for Arduino Raspberry Pi
I was looking for a high-end piece of furniture. a high-quality method of streaming audio from Spotify and my music library to a new set of powered speakers and subwoofer in the family room I chose to use an extra Raspberry Pi that was running the open source Volumio streamer software. Originally, I had a USB DAC (digital to analog converter) connected, but I wanted something smaller and potentially better quality. br>br>I got this for $8 at a thrift store. 00 DAC module with a Burr Brown PCM5102A chip, which is older but still very capable. If you can solder the included 6-pin connectors, it'll be much less expensive than a Hifiberry. To attach the header to the board, pin it to the board. It connects to the Pi via an I2S digital audio interface that is connected to the expansion port pins via six jumpers. The driver installation is handled by Volumio. In comparison to the USB DAC, it sounds fantastic. Because the PCM5102 lacks internal digital volume control, Volumio must scale the digital audio before sending it to the DAC, resulting in a slight loss of resolution and SNR. Unless you are an audiophile perfectionist, it is unnoticeable with the powered speakers and ambient noise environment. br>br>Instructions for connection are easy to find online. The default solder-on connector is a good choice. On the backside, pre-built bridged options are available. configured to run the Raspberry Pi flawlessly If you don't ground the "unused" SCK pin, your audio will be distorted or won't come out at all. You can also permanently ground the SCK pin by soldering a blob across the two pads near it, saving one jumper wire from the Pi. For the correct driver, select "HiFiBerry DAC" from the Volumio device options.
Let's get this party started. br>br>Because this module comes with no instructions, it will be extremely difficult for inexperienced users to get it to work. If you are truly inexperienced and manage to make it work, I guarantee you will learn a lot in the process, but that is the only guarantee I can make. Wiring: br>br> br>To get started, you'll need to connect it to the Raspberry Pi (I use the 4 pin connector, but others with the 40 pin connector should work as well - RT M) :
1 - 2 - VIN (red) - VIN (red) - VIN (green) - VIN (green) - VIN (green) - V GND (black) is connected to pin 6br>3. Pin 35 is occupied by LRCK (green). This is the only one on row 4 with an odd number. br> Pin 40br>5 - DIN (yellow) - DIN (yellow) - DIN (yellow) - DIN (yellow) - DIN BCK (blue) goes to pin 12br>br>You don't have to use the same colors, but I recommend using the red and black wires like I did so you know which one has power. Any scrap wire will suffice, but I used a USB cable salvaged from an old PC. If you use that method, you'll have to move the pins around the connector (which takes time). br>br>The red light on it will let you know if it's working after you've wired it up and turned it on. Have you made it to this point? Great! Now comes the difficult part! br>br>Installation: br>br>Installation: br>br> br>The Raspberry Pi operating system is unlikely to recognize it right away, so plan on doing a lot of Internet searching to make sure you have the right driver installed. It's pretty standard. After installing the drivers, remember to restart your computer. br>br>Sound Quality: br>br>
Ugh! By any stretch of the imagination, this isn't a good sounding DAC. I'd list about 100 adjectives to describe how bad I think it sounds if I had a better vocabulary, but instead, I'll just say it has that sound quality that people refer to as "elevator music. " br>br>In all fairness, this is a sub $15 DAC, so it's not about the sound quality, but rather about the ability to build and learn. A ten-fold return on your investment! br>br>Conclusion: br>br> br>To be honest, I adore this tiny module and had a great time putting it together. Instead of a sterile textbook-driven science class, every middle school student should be given one (along with a pi Zero) and told that learning how to make it do something will count toward their science grade. Even if it's just turning on the red light. I believe it is the ideal starting point for a 21st-century education. br>br>Thank you for taking the time to read this!.
Everything is properly labeled. It's purple as well! Everybody makes a breakout board for a popular chip. You can choose from a variety of color schemes: SparkFun is red, Adafruit is blue, and there are a few green ones (Seeed? ), but none of them are as cool as these purple ones. br>br>Put it under magnification and you'll see that the soldering is good, that there are no skewed parts, and that the construction is sound. Did I mention it's purple? br>br>Did I say it's purple?.
To get good sound, all 6 pins must be connected to the Raspberry Pi. To connect to sclk, use one of the available gnd pins on the pi. Pcm5102 is a high-quality chip from Burr Brown and Texas Instruments, and it should produce high-quality audio. You can also use the phat dac 1 line installer to configure your drivers. This will automatically set up Raspbian for you.
br>1. There were no instructions included with the productbr>2. The pin headers were included in the package, but you'll need to cut them down to size. br>3. With this point, I will save hours of troubleshooting. The product does not come jumpered in the back part of the pcb, so you will need to add the jumper to get it working. br>br>See the product image on the back of the pcb. br>br>I guess these small details can be improved.
I soldered this to my Pi Zero W and configured volumio to use a hifiberry dac, and it works perfectly. So far, everything appears to be working. I'll look for one with a hardware mixer next time so I can control volume without having to use the amp.
For $8, it appears to be a decent deal.
It's very simple to connect to a Raspberry Pi using online guides, and it sounds fantastic, far superior to the onboard audio!.
