A couple of days back, Raspberry Pi announced the four most popular IQAudio products to join the Raspberry Pi product line which, as the name suggests, are Audio add-ons. IQAudio previously sold expansion boards knowing the capabilities of Raspberry Pi for hi-fi audio. This is the relaunching of the DAC+, DAC Pro, DigiAMP+, and Codec Zero that will now be available for purchase via the network of Raspberry Pi approved resellers.
We came across so many announcements of HATS for Raspberry Pi in 2020 from audio add-ons to high-quality camera modules.
Due to high demand from the Raspberry Pi community, the RPI Foundation came up with the first hi-fi audio modules with this device ranging from audio I/O devices, amplifiers, and other accessories.
DAC+ is one of the low-cost audio output HAT with 24‑bit 192kHz high-resolution digital audio. This module is designed for all of the Raspberry Pi from Raspberry Pi 1 Model B+ onwards. It comes with a PCM5122 DAC from Texas Instruments that will deliver stereo analog audio to a pair of RCA connectors. The module also supports a dedicated headphone amplifier, which can be connected “to the analog outputs of audio DACs, to the outputs of self-made radios (for example using TDA7000, or TA7642) or other gadgets”.
To get started the board doesn’t need any external power supply rather it connects to the 40-pin general-purpose input-output (GPIO) header of any Raspberry Pi models (including 1 Model B+, 2, 3, or 4). If you are interested in buying the module, it will cost $20 via Raspberry Pi authorized resellers.
