PICO DSP is an open source, Arduino compatible ESP32 development board for audio and digital signal processing (DSP) applications. It offers a fully functional feature set for audio processing on a small format breadboard friendly device, and includes audio inputs and audio outputs, a low-noise microphone array, integrated test speaker option, additional memory, battery charge management and ESD protection all on the same PCB.
PICO DSP can be used for a wide range of digital signal processing applications, including but not limited to those in the fields of music, art, creative and adaptive technology. Music related examples include digital music synthesis, smart musical instrument design, mobile recording, Bluetooth speakers and wireless line-level directional microphones. Art related examples include sound-art installations, acoustic sensor networks and internet radio. Creative and adaptive technology related examples include voice user interface (VUI) design and web audio for the Internet of Sounds.

Form Factor and Connectivity
PICO DSP is a 100% open source project! The creators of this project believe strongly in the benefits of open source design and if you are reading this then we are interested in your contributions to the project too. PICO DSP was designed to create a reliable development board for audio applications with all the necessary hardware documentation easily available, and we believe there are currently unexplored applications of the hardware.
When the project launches, all the hardware design files (Eagle schematic and board files) and example software files will be available in a public repository on Github. As we progress through the campaign we’ll be having a look in more detail at the different aspects of the hardware design, and if there are any questions we’ll be on hand to answer them.
