Perfect for Voice AI Projects

This board is incredible for building voice-controlled assistants. The dual microphone array picks up commands clearly even from across the room, and the screen response is snappy. Setup with ESP-IDF was straightforward.

Good but runs hot

Functionality is great, but the board gets quite warm when running camera streams and Wi-Fi simultaneously. I had to add a small heatsink for long-term testing. Otherwise, it works as advertised.

Best Value Dev Board

I've used several ESP32 boards, but the Korvo V3 stands out for multimedia applications. The built-in screen saves so much wiring hassle. Highly recommended for smart home prototypes.

Excellent Audio Quality

The audio output is surprisingly clear for a development board. I used it to build a simple intercom system, and the latency was minimal over Wi-Fi. The XiaoZhi AI integration works well out of the box.
