ESP Audio Development Kits
ESP Audio Development Kits is a set of development boards designed to make audio development for ESP platform easy and feature-rich.
Key properties of this kit
- It uses ESP chips as a MCU core, which has huge community support and adaptation
- It delivers 2 channel amplified high quality audio ready to be connected to speakers of choice - no need to have external amplifier. Therefore it is all you need to complete your audio projecs
- It has low power consumption and built-in Li-Ion battery management - therefore it is a good choice for any sort of a portable and wearable audio projects.
- It has a rich UX peripheral, most obviously FTF screen with touch, but also IR receiver, and header for physical controls, like rotary encoder or joystick. Therefore it is a good choice for standalone user-facing audio projects.
