Custom ESP32 based audio PCB programmable using Arduino, esp-idf, faust and others. The board has USB C for programming and power supply and can alternatively be powered using 5v 2.1mm jack (center-positive), has an integrated MEMS microphone, a class D amplifier to drive small speakers, can be used as a USB audio class device (interface) and has WiFi, as well as Bluetooth.

The board was developed after having used both Teensy, Bela and other audio solutions, as well as ESP32 as a platform offering very easy access to WiFi and Bluetooth. This board aims to both be cheaper and combine audio with networking capabilities to be used in sound installations or other similar settings.
