Description:
Raspberry Pi Codec Zero is a Raspberry Pi Zero-sized audio HAT that delivers bi-directional digital audio signals (I2S) between a Raspberry Pi and the Codec Zero’s on-board Dialog Semiconductor DA7212 codec, and allows you to use a variety of input and output devices. With features such as programmable green and red LEDs, plus a tactile button for user input, Codec Zero makes a great starting point for audio projects such as a walkie-talkie, intelligent doorbell, smart speaker, or vintage radio hack. Previously known as IQaudio Codec Zero.
