The Pi-CodecZero
The Pi-CodecZero is a Raspberry Pi Zero sized board but it also includes the HAT’s EEPROM
allowing for auto configuration of the Linux environment if needed.
The Pi-CodecZero 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 / 8
Ω
).
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 Pi-CodecZero makes a great starting point for a walkie talkie / intelligent doorbell, vintage radio
hack or Smart type speaker.
