This TinyShield makes it incredibly easy to add audio support to your TinyDuino projects. It has an onboard DAC, filter, and amplifier for great sound quality. It can play any size uncompressed 22kHz, 16bit mono Wave files (.wav) directly off a microSD card (a microSD TinyShield is also required for this).
The audio output is mono on both the L and R channels, and uses a standard 3.5mm headphone jack connector. An onboard potentiometer can be used to control the volume. This TinyShield is completely compatible with the Arduino waveHC Library from Adafruit for playing wave files from a microSD card. This library is not compatible with SAMD21 processors, so this TinyShield is best used with the TinyDuino that uses the ATmega328p processor.
