lUCID lABS rASPBERY pi dac
The Lucid Labs Raspberry Pi DAC fits on Raspberry Pi 2 Model B and Raspberry Pi Model B+. Simply plug the female GPIO header on the Raspberry Pi DAC into the male header on the raspberry pi, change the sound output on your raspberry pi to i2S output and you have an audiophile quality analog output.
USB Digital to Analog Converters are the newest rage for audiophiles. These interfaces allow you to play extremely high-quality audio from your computer at much higher bit and sample rates than a standard soundcard. Most of these interfaces come with a hefty pricetag since it is pretty complicated to get a PCM data stream from a computer over USB. The Raspberry Pi, through configuration options allows you to send digital audio through its GPIO pins using I2S, a standardized protocol for digital audio. This allows you to have the same, or even higher quality, audio as expensive USB DAC interfaces at a fraction of the cost since it removes a large number of components and complexity from the interface.
Our interfaces use the Texas Instruments PCM5102A 32bit/384khz DAC chip. These chips have a listed Signal-to-Noise ratio of 112dB and THD+N of -93dB. We have also used the Texas instruments ultra-low noise linear voltage regulator TPS7A4700 which provides the DAC with an extremely clean power supply. The result is excellent sounding audio. Using free software like Volumio you can build a network connectable audio player for as little as the cost of a Raspberry Pi 2 model B ($35 USD), the cost of a lucid Labs Raspberry Pi DAC, and the cost of a micro SD card. Commercial products with the same features...network connectivity, high quality DAC, Smartphone and computer control from a local network cost upwards of thousands of dollars.
Each Lucid Labs Raspberry Pi DAC comes fully assembled (Made in the USA) and includes mounting stand-offs so that it can be securely mounted to your raspberry pi. Each unit is 100% tested prior to shipment.
