Description

The Codec Zero is the same size as a Raspberry Pi zero but designer for audio signal input and output processes. It supports a range of input and output devices from built in MEMS microphone, mono Electret microphone or mono speaker (1.2W 8Ω).

Details

The Codec Zero is a Raspberry Pi Zero sized board that 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 the onboard Dialog Semiconductor DA721. This allows for it to support a range of input and output devices from built-in MEMS microphone, mono Electret microphone or mono speaker (1.2W 8Ω).

The device also has GREEN (GPIO23) and RED (GPIO24) LEDs, that can be used for status. As well as a tactile button GPIO27 that can be used to start an event.

If you’re looking for a new project, the Codec Zero makes a great starting point for a walkie talkie, intelligent doorbell, vintage radio hack or Smart type speaker.
