# Teensy-Haptic-Audio-Player

![the PCB](hardware/hapticscreenshot.png) 

A PCB designed for audio and haptic projects with [a Teensy 4.0](https://www.pjrc.com/store/teensy40.html). 

Among other things, it can be used to play audio from the computer as a sound card when connected via USB or from audio files via the on board SD card reader. The audio will then be output both to a 3.5mm audio jack and a haptic driver that will make a vibration motor [like this one](https://www.adafruit.com/product/1201) vibrate in sync with the audio, kinda like in a gamepad, sex toy or phone.

Another usecase is simply as a high quality audio development platform.

The whole thing is open source and hackable and is designed to be used for many different scenarios.

See [hyaline.systems](https://hyaline.systems) for more information. 

## Buying

You can buy a board, either bare (no components) or SMD-populated (no Teensy included) by sending an email to [[email protected]](mailto:[email protected]).

If you just want to support the project, [consider making a donation through kofi](https://ko-fi.com/madskjeldgaard).

## Features

- Designed for the very powerful Teensy 4.0 board.

- High quality i2s stereo output DAC with 3.5mm line out jack: [PCM5102A DAC](https://www.ti.com/product/PCM5102A) – this DAC is widely compatible with all platforms and SDK's, including Arduino and C.

- SD card reader

- NeoPixel

- StemmaQT connector for easy i2c expansion.

- Optional: Hardware mute button may be connected directly to DAC.

- All unused pins broken out with lots of ground and power pins to make external connections easy

- Self-documenting board: All pins and connections are written on the board itself.

## Software

See [software/examples](software/examples) for example code using Arduino.
