  1. CODEC Wing

    Lol, you're right about the orientation, I should have noticed that before I ordered it... anyway It's just a prototype. I'll upload pictures when the PCB arrives (hopefully next week). Maybe next time I could use a single CODEC chip like offroad suggested and make it a little bit smaller
  2. CODEC Wing

    Hello. Some time ago I posted a topic about a DAC Wing that I made (using the MAX5556), and well... So far it has been a total failure. I don't know if I damaged the chip while soldering or what is happening, but it simply does not respond (I soldered 2 and none of them seem to work). That's why I decided to try a different chip. This time I chose a PCM1754 from Texas Instruments. And since I also decided to manufacture the PCB with Elecrow (last time it was with OSHPark), I had some room left, so I decided to throw in an ADC as well, making it a CODEC Wing . The ADC is a PCM1808, and to generate the proper clock signals for standard sampling rates (44.1kHz, 48kHz, etc.) I used a PLL1705. Here is the render of the PCB I'll attatch the schematic as well. What do you think? Here is the link of the github of the deisgn files and stuff https://github.com/DiegoRosales/PCB_Designs/tree/master/CODEC%20Wing CODEC Wing Schematic Rev 1.0.pdf
  3. MAX5556 Audio DAC Wing

    I'm first going to try with the Microchip ENC28J60 and see how it goes
  4. MAX5556 Audio DAC Wing

    Yep, I used Kicad. . I ordered some free samples of the chip, but the pcb has not arrived yet. I'll let you know how it went.
  5. MAX5556 Audio DAC Wing

    Hello. I'm working on a MAX5556 Audio DAC Wing and I thought I should share it here . It (obviously) has a MAX5556 Stereo DAC at its core, with an I2S-compatible interface and up to 50KHz sampling rate (perfect for standard 44.1 and 48 KHz sampling rates) and a resolution of 16 and 24 bits. The board does not contain any output buffer as I wanted the board to be as small as possible. It only has the MAX5556, a couple of passives and a 3.5mm stereo jack. I'll leave you with the schematics and a render of the board. Any criticism is well accepted I'm also prototyping a Megawing with an ADC, a DAC and an Ethernet controller to stream audio over ethernet. Schematic.pdf
