Codec Zero is a module with dimensions equal to Raspberry Pi Zero. The cover plate is equipped with a speaker output (mono), audio jack connectors to connect an electret microphone, built-in MEMS microphone and AUX IN and OUT pins. There is also a general purpose button on the board. The sound card is based on DA7212 chip, which allows for Hi-Def 96 kHz / 24-bit audio playback. IQaudIO has been taken over by the Raspberry Pi Foundation providing further support for Raspberry Pi users.
