Perfect starter kit for AI voice projects

This board is incredible out of the box. The Xiaozhi AI chat function works smoothly over 4G without needing complex Wi-Fi setup. The 16MB flash gives plenty of room for custom firmware if you want to modify it later.

Great hardware, documentation could be better

The ESP32-S3 chip is powerful and the 4G module connects quickly. I love the included screen and case. However, the English translation in the manual was a bit sparse, so I had to rely on community forums for advanced configuration.

My first IoT success

I am new to embedded systems and this kit made it easy. Plug in the SIM card, charge the battery, and it starts chatting immediately. It's a fantastic learning tool for understanding IoT connectivity.

Ready for customization

While the pre-loaded AI is fun, the real power is in the ability to flash your own code via Arduino IDE or ESP-IDF. The pinout is standard and accessible. Highly recommended for prototyping smart devices.

Solid build quality

The PCB layout is clean and the components are well-soldered. The 4G antenna performance is surprisingly good indoors. Only minor issue is the speaker volume could be slightly louder for noisy environments.

Excellent value for money

Getting an ESP32-S3 with 8MB PSRAM, a screen, a case, and a 4G module for this price is unbeatable. The voice recognition latency is very low, making conversations feel natural.
