The Pico Audio is an audio expansion module and speaker set designed for the Raspberry Pi Pico. The module incorporates a CS4344 low-power stereo decoder and uses the I2S bus for transmitting audio signals. It supports a wide range of audio sampling rates and allows 3.5mm headphone and speaker signal output at the same time via the onboard APA2068 amplifier! The board includes a small volume control dial and audio decoder observation pads. A set of 8-ohm 5W speakers are included which come with a 4-pin connection that matches the onboard connector. Raspberry Pi Pico not included. You'll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
