IQaudio Codec Zero is a Raspberry Pi zero-size audio I/O HAT. It provides bidirectional digital audio (I2S) between Raspberry Pi Zero and its integrated Dialog Semiconductor DA7212 codec. Codec Zero supports a range of input and output devices, from built-in MEMS microphones to external monoelectret microphones to 1.2 W and 8 ohm mono speakers. The IQaudio Codec Zero has green and red LEDs that can be used for status, as well as a tactile button that can be used to start an event. Codec Zero is a good starting point for a walkie-talkie, smart doorbell, vintage radio hack or smart speaker. Note - see datasheets for more useful installation information. https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2021-06-14 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2022-10-05 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2022-10-19 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2023-04-17 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2023-05-11 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2023-08-16 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2024-07-29 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2025-04-08 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2025-11-25 https://elecena.pl/product/18808207/iqaudio-codec-zero-raspberry-pi-shield-iqaudio-codec-zero 2026-02-20
