Schematic for Audio Tutorial Kit

[a.bis]

Hello everyone,


I am currently building an audio project using the Teensy 4.1. While researching, I came across Paul’s excellent tutorial and the complete project based on the Teensy 3.2. It has been an invaluable resource for understanding the Audio Library and overall project structure.


However, I have not been able to find the schematic for that project. I was wondering if anyone could share the original schematic or, even better, an updated version for the Teensy 4.1.


I am particularly interested in a schematic that includes the Teensy 4.1, the Audio Adapter (Audio Shield), and common peripherals such as potentiometers, push buttons, a TFT display, and any other supporting components used in the project.


If such a schematic or reference design is available, I would be very grateful if you could point me to it or share it.


Thank you very much for your time and assistance.

Paul's tutorial is an excellent way to get started with audio on Teensy.

I am not aware of a schematic for the original tutorial as the breadboards came preassembled or were assembled using breadboard coordinates, but this schematic below might help you get started. It is based on the original Audio Tutorial and is using a Teensy 4.1.

There is no LED shown on the schematic as this setup is using one already connected to pin 5 of the Teensy 4.1, which is the same as the tutorial. It is just an LED with the anode connected to Teensy 4.1 pin 5 through a 470 ohm resistor and the cathode is connected to ground.

Also ignore the CN1 connector which is used to plug this adapter board into a Teensy 4.1 baseboard.

That baseboard setup doesn't use a separate Audio Adapter, but instead uses the same circuit built into the baseboard itself along with an LCD, and other stuff. You might find those schematics useful as a reference for your own work and it can be found near the bottom at this link: https://protosupplies.com/product/mini-platform-teensy41/
