ESP32 Audio Development Board is an audio platform supporting Wi-Fi and Bluetooth

An electronic hobbyist and a maker, Andriy, has designed an ESP32 Audio Development Board based on the famous LX6 microprocessor, which has been widely used for a variety of edge devices because of its increasing community support. The board allows for a wide range of user interaction as it comes with a rich set of peripherals. The project is expected to go live very soon on the CrowdSupply website, looking for some crowdfunding support.

As the hardware is designed to deliver two-channel amplified audio that can be readily connected to a speaker– there is no need for an external amplifier. A fully-featured touch screen version and a portable tiny version of the ESP32 Audio Development Board will be available.

The audio development board’s built-in integrated Li-Ion battery management attributes to the board’s minimal power consumption, making it an excellent solution for any portable or wearable audio project. Furthermore, it includes a TFT touch screen, an IR receiver, and a header for physical controllers such as a rotary encoder or joystick. Hence proving to be a perfect fit for standalone audio applications with a user interface.

Specifications of the ESP32 Audio development Board

  • MCU Core: ESP32 dual-core LX6 microprocessor clocked at a frequency of 240MHz
  • Memory: 8MB RAM
  • Storage: 16MB flash storage and can be expanded using onboard SD-card slot
  • Battery: Supports Li-Ion and Li-Po BMS
  • Audio amplifier: Maxim Integrated MAX98537 with built-in Class-D amplifier
  • Peripherals:
    • Screen: 2.8-inch TFT screen with touch sensor
    • Wireless connectivity: Wi-Fi and Bluetooth
    • LED: RBG LED and strip header
    • Header: JTAG header, Joystick header

Note: Some of the specifications have changed for the mini version.

Due to its small and compact size, the device can easily fit inside any hardware system for space-constrained applications. It can also be used as Wi-Fi or Bluetooth portable speakers, a Wi-Fi radio, and a smart speaker using any preferred platform such as Spotify. The audio development board can even be utilized for talking devices and audio-based wearables that are wirelessly connected.
