Raspberry Pi Turns Its IQAudio HATs Green

Posted on

Raspberry Pi has revamped many of its audio add-ons, replacing the previously black PCBs of the HATs with green ones to match the SBCs they’re paired with. There are a few minor layout and connector alterations too, but otherwise, the boards remain functionally unchanged. In a blog post (opens in new tab), Raspberry Pi-maker Eben Upton explained what’s going on.

The audio HATs sit on top of a Raspberry Pi (opens in new tab) board with GPIO, such as the Raspberry Pi 4 (opens in new tab), connecting to its GPIO pins and adding high-quality amplifiers, DACs, and phono outputs. IQaudio was founded in 2015 to create better quality sound products for Raspberry Pi boards used for things like streaming audio in stores and other businesses. However, it was absorbed into Raspberry Pi (opens in new tab) in 2020.
