I got goosebumps when I heard this audio chip because of its clarity. I messed around with this chip for a day trying to figure out how to connect it to an ESP8266, but then I came across a hackaday "do it yourself audio dac hat for the pi zero" that provided a clear, simple interface diagram, and I was up and running in a matter of minutes. I, too, was disappointed that diymore was unable to provide instructions. If you ask for instructions, you'll only get the chip's TI pdf, which I could get on my own. I took a star off because that made no sense, diymore. br>br>You can easily connect a good pair of headphones to the DAC and enjoy noise-free hi-fi. fidelity audio that revealed parts of songs that I had never heard before, at least for me. From now on, this will be my go-to DAC!.
This is an excellent board. I put it to the test with both an ESP32 and a Raspberry Pi. Because of the high impedance requirements, the chip is not designed for headphone output, but it can be tested with one. There is no hardware volume control, but if you upscale the input signal to 32-bit, you can adjust the volume. A software volume control, on the other hand, will work well without sacrificing too much quality. Select "Hifiberry DAC" from the settings if you want to use it with Volumio.
To begin, I'd like to point out that the specifications listed are incorrect, but that's okay. Texas Instruments' PCM5102A DAC is used on this board. It supports 24-bit, 192-kHz audio, according to the listing. The DAC supports 32bit 384kHz audio, according to its specifications. I eventually found an uncompressed audio file mastered at that resolution and bitrate after some Googling. After that, I used a C-connector to connect the DAC to my PC. I bought a USB to IIS converter board somewhere else. The audio quality was outstanding! This board did a far better job of reproducing the audio than I had anticipated. It was almost as if I was there. Overall, the audio was much cleaner than anything I'd heard before, and this was evident across the entire frequency range of the file I was listening to. The bass notes were clear and powerful. The higher frequencies were also as clear as the lower ones, with no distortion. The high bit depth brought the performance to life, allowing you to hear not only the music but also subtle nuances like the sound of a guitar string hitting a fret. It reintroduced the human element into music in a big way.
Because there is no documentation for these, I have no idea how good they are. There is only one example code for using similar boards, but compiling it is a pain because it isn't written in Arduino or any other common programming language. As a result, I would not recommend this product until more information and sample code are available.
I'll save you the time and effort I had to put into mindless googling and reading. Simply follow the online instructions and run the i2s amp install script on your Pi. The sound quality of the DAC is excellent.
Refer to one of the reviews for a connection diagram.
Once I receive a wiring diagram from the seller, I will update my review. br>br>This module can be purchased from a variety of'stores,' but none of them include a connection diagram! I'm attempting to guess (so far, the number 3 appears to be the correct answer). You don't want to FEED your own 3v line because it's an OUTPUT from a local ldo. 3 volts into that and the vcc line appears to be a shared line for analog and digital, and I - think- Because there is a 3. 0 volt supply, you can send 5 volts to the vcc pin. The vcc pin is used to power a 3v ldo. It's unclear whether I need to ground the 'default' pins (FLT, etc. ) or not. br>br>Once again, I'm hoping that the vendor will intervene and send or even POST a connection diagram or schematic. When are they going to learn? With our hardware modules, we are entitled to documentation. It's not fair to make us look for these documents when the vendor could have included even just a short url to where the documents are located in the mailed-out package. br>br>update: br>br>update: br>br>update: After exchanging a few emails with the seller, it is clear that they are unwilling to release information that would allow a DIYer to properly connect/interface with this board; they believe that by disclosing this information to their customers, competitors would steal their design. sigh. So, I guess I'll just return it because it's become too much of a hassle, and to be honest, I don't enjoy fighting with a *diy* vendor just to be able to *use* his product. br>br>downrated to 1 star. I'm giving it a 'do not buy' rating, and I'm not going to buy anything from diymore again.
