The Pico-Audio is an audio expansion module designed for Raspberry Pi Pico, which incorporates PCM5101A low power stereo decoder, and uses I2S bus for transmitting audio signal. It supports wide range audio sampling rate, allows headphone and speaker signal output at the same time.

• Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series
• Standard 3.5mm audio jack, for connecting external headphone
• Dual channels speaker headers, for direct driving speakers
• 8~384000Hz audio sampling rate
• Stereo sound effect output
• Using 3-wire I2S, effectively reducing EMI
• Comes with development resources and manual (Raspberry Pi Pico audio play code, sound card code)
