The Open Source Hardware Association (OSHWA) runs a free program that allows creators to certify that their hardware complies with the community definition of open source hardware. Whenever you see the certification logo, you know that the certified hardware meets this standard. The database has over 3,000 boards to date!

This month’s four highlighted boards includes the Adafruit TLV320DAC3100 I2S DAC, UID US002729:

Adafruit’s TLV320DAC3100 I2S DAC is enchanting to the ears! This little gem offers stereo headphone and mono speaker output, delivering crisp, top-notch audio directly to 16-ohm headphones and 4-8 ohm speakers without the need for an external amplifier. Perfect for all-in-one audio projects!

Though it doesn’t need a MCLK signal and can use BCLK as the PLL input, it does require some I2C magic. Fear not, adventurers! A microcontroller paired with Adafruit’s library (compatible with Arduino, CircuitPython, or Python) will set the stage for your audio marvels.
