Loud ESP is an ESP32-powered, rich-audio development board. Available with or without a color touchscreen, Loud ESP has a wealth of peripherals to support a wide range of user interaction. It is compact, portable, battery-powered, and designed to accommodate a variety of enclosures, all of which make it an ideal platform for the development of wearables and other smart devices. To help out with that, we maintain a repository of sample code that you can adapt for your own applications.

Wireless, Touchscreen-Enabled Versatility for Audio Applications

Loud ESP is well suited for a number of different applications. To name just a few examples, it can be used as a portable speaker system with Wi-Fi and Bluetooth capability, an internet-radio receiver, a framework for developing wearables and talking gadgets, or a smart speaker connected to the platform of your choice, such as Spotify.
