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. It 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 microphones, mono Electret microphones,s or mono speakers (1.2W 8Ω).
The Codec Zero delivers bi-directional digital audio signals (I2S) between the Raspberry Pi and onboard Dialog Semiconductor DA7212. 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.
