The Raspberry Pi has revamped many of its audio add-ons, replacing the HAT’s previous black PCB with a green one that matches the SBC it’s paired with. There are also some minor layout and connector changes, but other than that the functionality of the board is unchanged.of blog post (opens in new tab)Raspberry Pi maker Eben Upton explained what was going on.
Audio HAT sits on top of Raspberry Pi (opens in new tab) A board with GPIO such as the Raspberry Pi 4 (opens in new tab), connect to its GPIO pins and add high quality amplifiers, DACs and phono outputs. Founded in 2015, IQaudio creates quality sound products for Raspberry Pi boards used for things like streaming audio in stores and other businesses.But absorbed by Raspberry Pi (opens in new tab) 2020.
The Raspberry Pi 4 can output sound via Bluetooth, HDMI output, and 3.5mm headphone jack, but the Audio HAT improves this.the smallest is codec zero (opens in new tab), 24-bit 96kHz Dialog Semiconductor DA7212 DAC, built-in and external microphone input sockets, mono speaker terminals, and stereo input and output channels. This is useful for projects such as walkie-talkies and smart doorbells. Or check out the funny chatterbox created by the Raspberry Pi team in the video above.
of Digi-AMP+ (opens in new tab) Holds Texas Instruments TAS5756M stereo amplifier and stereo speaker output. It also powers the Pi board, although it requires its own external power supply. Choose this if you want to turn your Pi into a hi-fi system. There is also a pair of DAC boards. DAC+ (opens in new tab) and the DAC Pro (opens in new tab)Both have headphone amplifiers and sockets, but the DAC Pro adds a balanced/differential output in parallel to the line outputs.
The new boards are manufactured in the UK but are available worldwide from authorized resellers. The layout changes are intended to make the board simpler and faster to manufacture. The only big difference is that the PCB is now green.The raspberry pi has specs Comparative material (opens in new tab) Help you choose the audio board that best suits your needs.
