## Description

Features:Made of high quality electronic components, it is solid, durable, good conductivity and high performance, long service life.Its I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface.Its logic level is 3.3 - 5V(a rarity), and can be used to process multiple different formats by setting two pins to high or low.And DAC can process data immediately, and give you a clear, analog, stereo line level output.It's even cool with MCLK-less I2S interfaces such as the Raspberry Pi (which it's ideal for), a built in PLL will generate the proper clock from the incoming signal.For inputs, you can use classic I2S (the default) or 16-bit, 20-bit or 24-bit left justified data.And you can set it up to take an input system/master clock, but we default-set it to just generate it for you.So you only need to connect Data In, Word Select (Left/Right Clock) and Bit Clock lines. If you want, there's a mute pin and a de-emphasis filter you can turn on.Decoder board only, other accessories demo in the picture is not included!Specification:Material: Circuit Board, Electronic ComponentVoltage: 3.3-5VSize: app.3.6 x 2.6cm/1.42 x 1.02inColor: PurplePackage includes:2 x Decoder Module2 x Pin Header
