Dettagli

This is the Teensy Audio board add-on for the Teensy 3.0 and 3.1 development boards. This audio board provides you with an easy-to-use tool to add high quality 16 bit, 44.1 kHz sample rate audio to your Teensy project. With the audio library provided in the Documents section below you will be able to use both the input and output simultaneously in order to make a variety of great audio projects, incorporate synth waveforms, effects, and mix multiple sound streams and cd quality audio to your headphones or different line outs!

The Teensy Audio board utilizes the SGTL5000 stereo codec with headphone amp IC to decode and drive audio files and the Cortex-M4 DSP instructions from the Teensy dev board to provide power to a real-time FFT. Each board is also equipped with 3.5mm audio jack for headphones, a micro-SD card slot for storing audio files, and optional spaces for a 25k potentiometer (volume control) and flash memory chip. The two rows of 14x1 headers are not included to give you the freedom to choose how to connect your audio board with your Teensy.

Features:

  • 16 bit, 441 kHz Sample Rate Audio
  • Plays Uncompressed WAV and Raw Audio Files
  • 4 Channel Software Mixer
  • 3.5mm Audio Jack
  • micro-SD Card Slot

Questions on Teensy Audio Board

  • 20/08/19 17.44 Buongiorno ... mi è appena arrivata a casa il nuovo Teensy 4.0 volevo chiedervi se la scheda Audio Board per i Teensy precedenti è compatibile con il nuovo 4.0 (ho letto che cambiano i pin ma questo non è un problema) ma la domanda più importante è con il nuovo 4.0 è/sono per caso presenti al suo interno chip audio I2S ? che possono essere utilizzati al posto della scheda Audio Board esterna ? Grazieeeeeee Enrico
    • Salve, il Teensy 4.0 ha 2 porte I2S, il Teensy 3.0 ha una porta I2S. La scheda Audio Board serve a fornire una uscita analogica e un lettore di schede SD, e' una soluzione pronta.
      Per quanto riguarda la compatibilita' della Audio Board, riporto una nota del produttore:

      Update: Teensy 4.0 has its digital audio signals (MCLK, BCLK, LRCLK, TX, RX) in different locations. On Teensy 3.x, these are pins 11, 9, 23, 22, 13. On Teensy 4.0, those signals are pins 23, 21, 20, 7, 8. This audio shield will only work if wires are used to route those 5 signals. It does not work if soldered directly above or below a Teensy 4.0. The MCLK signal also requires a 100 ohm resistor in series. We added this resistor in "Rev C", which is currently shipping, but not yet documented on this page. If you have an older "Rev B" audio shield, you will need to use a 100 ohm resistor in line with MCLK to use it with Teensy 4.0. We are working on a "Rev D" audio shield with the 5 signals routed for Teensy 4.0, for release in early September.
