A new era for the coveted Raspberry Pi family: hi-fi audio is finally here!

 Raspberry Pi's Redesigned Audio HATs Turn Its IQAudio HATs Green 

Raspberry Pi made the announcement that all four boards have been upgraded. The biggest difference between them and the earlier blackboards is that they all utilize green boards, which makes them "a bit more Raspberry Pi-like." This continuous design-for-manufacturability work is the distinguishing feature of all Raspberry Pi products, according to the announcement, which also mentioned "a few minor layout and connector changes, aimed at making the boards simpler and quicker to manufacture."

Some music aficionados use a Raspberry Pi instead of spending hundreds of dollars on hi-fi streaming equipment. That's correct; using a cheap Pi computer, you only need a DAC to completely transform your home audio. Additionally, there are several official choices available.

Two years ago, the Raspberry Pi Foundation started selling DAC HATs. These HATs enable the addition of analog audio components to a Raspberry Pi computer. For example, you might use a Pi DAC+ to link your Raspberry Pi to an amplifier or an A/V receiver.

There is also the Pi DigiAMP+, a HAT with an inbuilt amplifier if you wish to use your Raspberry Pi with passive speakers. These parts are pretty useful and are frequently used in music streamer projects. (One of my preferred projects transforms the Raspberry Pi into a touchscreen music streaming user interface.)

The Raspberry Pi Foundation provides the following high-end HATs:

• $20 for a Raspberry Pi DAC+
• a $25 Raspberry Pi DAC Pro
• DigiAMP+ for Raspberry Pi: $30
• $20 for a Raspberry Pi Codec Zero

On December 2nd, these HATs had a little change, which is why we're spotlighting them right now. Naturally, the majority of this change is cosmetic. The hi-fi HATs have been somewhat re-engineered to simplify production and now utilize a green circuit board (rather than a black one). (From a functional standpoint, the upgrade makes no modifications to these boards.)

When buying from a merchant, you could get a revised hi-fi HAT, according to the Raspberry Pi Foundation. However, this is not a given. The old blackboards are still available at stores, so it could be a while before they run out.

The products page for Raspberry Pi lists all of its audio components. Be aware that the Raspberry Pi Foundation does not conduct direct business with customers. You must buy this stuff from a merchant like CanaKit.
