IQaudio Codec Zero
IQaudio Codec Zero is a Raspberry Pi Zero-sized audio I/O HAT. It delivers bi-directional digital audio signals (I2S) between Raspberry Pi Zero and its onboard Dialog Semiconductor DA7212 codec. Codec Zero supports a range of input and output devices, from the built-in MEMS microphone to external mono electret microphones and 1.2W, 8Ω mono speakers.
IQaudio Codec Zero has GREEN (GPIO23) and RED (GPIO24) LEDs that can be used for status, and a tactile button (GPIO27) that can be used to start an event. Codec Zero makes a great starting point for a walkie talkie, intelligent doorbell, vintage radio hack, or smart speaker.
IQaudio Codec Zero has undergone extensive compliance testing and meets the standards required in many countries. You can find all compliance information and regional certificates at pip.raspberrypi.com.
IQaudio Codec Zero will remain in production until at least January 2026
