Features At A Glance
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)
Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- I2S
- I2S is a digital audio interface used to send sound data between chips, such as from a microcontroller to an audio amplifier or DAC. It matters if your project needs cleaner digital audio output than a basic buzzer or PWM signal can provide.
