S/PDIF optical output for Teensy 3.1.
Parts Required:
Everlight PLT133/T6A connector, Digikey 1080-1434-ND
Capacitor, 0.1 uF, 0805 size, Digikey 1276-1003-1-ND
The Teensy Audio library now officially supports S/PDIF output. WAV File Player Example (in Arduino: File > Examples > Audio > WavFilePlayer) has been updated to show how to use it.
The S/PDIF output object is now available in the Audio System Design Tool, so you can easily create arbitrarily complex audio projects with digital S/PDIF output.
Special thanks to Frank Boesing for developing the S/PDIF encoding code!
Ongoing development conversation here:
The S/PDIF signal is output on pin 22. An inexpensive connector (Digikey 1080-1434-ND), or simply a red LED, can be used to couple the digital audio to an optical TOSLINK cable! Resistors and a small transformer can also be used, for non-optical RCA connector S/PDIF.

Simple breakout board for the ESP8266 chip to provide wifi capability to the Teensy 3.1. Designed to take power from VIN via USB or LiPo battery and convert to 3V3 with a TLV7333 300 mA voltage regulator. Also on board is a Macronix 4 Mbit MX254006E SPI Flash memory chip. Small rgb led indicates power on, pcb antenna matched to 2.4 GHz. Can use either 26 or 40 MHz Seiko Epson crystal. The board has the same eight pins as the cheap Chinese modules as a first cut to see how hard it is to add wifi to Teensy 3.1 projects. The board is designed to solder directly on top of the Teensy just above the USB plug. Added led on TX, broke out five more GPIO pins including SPI port.
