Retired Product

This product has been retired and kept here for reference.

This audio adapter lets you easily add high quality 16 bit, 44.1 kHz sample rate (CD quality) audio to your projects with a Teensy 3.0 or 3.1. It supports stereo headphone and stereo line-level output, and also stereo line-level input or mono microphone input.

The audio chip connects to Teensy v3 using 7 signals. The I2C pins SDA and SCL are used to control the chip and adjust parameters. Audio data uses I2S signals, TX (to headphones and/or line out) and RX (from line in or mic), and 3 clocks, LRCLK (44.1 kHz), BCLK (1.41 MHz) and MCLK (11.29 MHz). All 3 clocks are created by Teensy3.1. The SGTL5000 chip operates in "slave mode", where all its clock pins are inputs.

As of February 23rd, 2015 Adafruit are shipping an updated version with a few minor changes.

This product does NOT include a Teensy, it's just the audio adapter!
