IQaudio sound cards are all designed to work with the current Raspberry Pi and those that have a 40way male GPIO pin header. This includes Raspberry Pi 4B, 3B+, 3A+, 3, Zero etc. Some of our products are full-size HAT boards for the full-size Raspberry Pi, and others are more suited to the Raspberry PI Zero form factor.

Codec Zero is a Raspberry Pi Zero sized board but it also includes the HAT EEPROM allowing for auto configuration of the Linux environment if needed.

The Codec Zero delivers bi-directional digital audio signals (I2S) between the Raspberry Pi and onboard Dialog Semiconductor DA7212. Supporting a range of input and output devices from built in MEMS microphone, mono Electret microphone or mono speaker (1.2W / 8Ω).

It also 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.

The Codec Zero makes a great starting point for a walkie talkie / intelligent doorbell, vintage radio hack or Smart type speaker.

• P1 and P2 will support external PHONO / RCA sockets if needed.
• P1: AUX IN, P2: AUX OUT.
