    I kinda agree, it's a little extreme. It was a good learning experience though. I'm now working on placing the chips I want to use directly onto the board, and skipping the Breakout Board altogether. It was helpful in...

    I'm designing based on the FreeDSP Expansion Connector. I thought about adding 3.3 and 5v to the FreeDSP connector (at the end of the connector), but people on DiyAudio.com suggested not to. Some said that it...

    Hello, My project requires a Bluetooth A2DP Sink that is the fed to the Teensy 4 via I2S. I'm leaning towards an ESP32 chip connected to the Teensy for both control over its Bluetooth pairing functions, as well as...

    Can you please post a link to he right datasheet? I'm also not finding the 5 data pins on the first SAI. I did find a note about 4 data pins in the application note but not 5. I wanted to read up about switching the...

    Paul, can you please confirm that the exposed USB pins (other than the one hard soldered on) can be configured to effectively operate the same way? Are the two USB pins interchangeable? Can they both work the same way?...

    I agree, microusb is easily broken. I prefer 5 pin USB headers, so I can connect my own USB port. Pro audio gear still uses USB B for devices. It's much larger and robust. So I would likely try to remap the USB. Even...

    From the PCM5102A datasheet, "The serial audio interface typically has 4 connections SCK (system master clock), BCK (bit clock), LRCK (left right word clock) and DIN (data). The device has an internal PLL that is used...

    The PCM5102A doesn't have software control, it's a hardware DAC. You'll have a digital volume, processed by the Teensy. Place it inline of the audio project on the audio design tool. Then you can read your PC's volume...

    OK, I'll still incorporate it into my breakout board. Then when there is time or interest, it will make testing easier. Does the schematic look right? Thanks Paul. I'm excited to work with this new board.

    In case you missed it, I documented the connections in a previous post. It seems to have resonated with many people because I hear about this chip being used with the Teensy a lot. :-)

    I'm working on an Audio Breakout board and it will have TOSLINK SPDIF. Let me document my findings. - There is an Optical Audio Output Board for Teensy 3.1 at OshPark. - There is a discussion about using WM8804...

    Well it's nice to meet you. I'm far from being a professional engineer. I'm self taught, just trying hard to get what it is I want. I'm glad we connected. Maybe we can help eachother out. We seem to have some similar...

    Hi Mike, You've certainly peeked my interest with the PI4. I'm interested in all things audio. Live pro audio is my background, and I'm working on gadgets to create my own pro audio mixer. My goal is to create a...

    Do you use the PI4 for real time audio processing? Is this through some OS, or bare metal? I feel like the teensy 4 is very well optimized for this (real time requires low latency). I wonder how the teensy stacks...
