Raspberry Pi IQaudIO HAT-Compliant Sound Cards
Raspberry Pi IQaudIO Hardware Attached on Top (HAT) Sound Cards deliver high-fidelity audio to existing Raspberry Pi-based projects/equipment. The plug-and-play devices include a pre-programmed EEPROM allowing Raspberry Pi OS to auto-detect and auto-configure itself. These sound cards each have a specific purpose and set of features while supporting 24-bit depth. The DAC+ and DigiAMP+ boards offer high-quality playback with support for up to full HD audio (192kHz). Ideal for compact projects, the Codec Zero supports up to HD audio (96kHz) and includes a built-in microphone.
