Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem.
- It can play up to 22KHz, 12bit uncompressed audio files of any length. It's low cost, available as an easy-to-make kit.
- It has an onboard DAC, filter and op-amp for high quality output.
- Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.
- This shield is a kit, and comes with all parts you need to build it.
Arduino, SD card, tools, speaker and headphones are not included.
