Raspberry Pi single-board computers are still wildly popular, with uses ranging from learning programming to DIY electronics. Now there’s an updated lineup of hi-fi audio cards that can turn a Pi into a better media station.
The company behind Raspberry Pi acquired IQaudio two years ago, which was already producing four external DACs compatible with various Pi boards. The accessories allowed Pi devices to output powerful and higher-quality audio, ideal for home theater setups, music studios, or anywhere else audio quality is a priority.
Raspberry Pi announced today that it has updated all four boards. The most noticeable change is that they all use green boards, making them “a bit more Raspberry Pi-like” compared to the older black boards. The announcement also mentioned “a few minor layout and connector changes, aimed at making the boards simpler and quicker to manufacture: this sort of continuous design‑for‑manufacturability work is the hallmark of all Raspberry Pi products.”
The lineup consists of four boards. First is the $20 DAC+, which provides stereo analogue audio and a dedicated headphone amplifier. There’s also the $25 DAC Pro, with a better Texas Instruments chip for a higher signal-to-noise ratio, and the $30 DigiAMP+ has an integrated digital-input amplifier. Finally, the Codec Zero is a $20 board designed specifically for the Raspberry Pi Zero.
It’s great to see Raspberry Pi invest in better audio support for projects using Pi boards, but the elephant in the room remains — the actual Pi boards themselves are still remarkably difficult to purchase. Demand for Pi boards has outstripped supply for well over a year now, with many people venting their frustration on social media. There’s even a third-party tracking site for finding restocked store listings.
