One (1) Pioneer TS-A878 3.5" 2-Way Speaker (not shown)
Fully programmable, using the Arduiono Uno, the Wave Shield plays up to 22KHz, 16-bit, mono (yes... mono) PCM (.wav) files. It's a low cost, small package, has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card. Volume can be controlled with the optional on board thumb-wheel potentiometer.
The amplifier is a mono IC amplifier, using a TDA2030 IC with 8 Watts output. This amp runs off of 12VDC, has a 94 dBA signal/noise ratio and a 20Hz to 20kHz frequency response, all in a small, low cost package.
This is my Droid's Primary Sound System with the Secondary System being the audio portion of the Hasbro Interactive R2 conversion. | |
