Fast inference speeds
I tested several quantized models on this N16R8 configuration, and the inference speed is remarkable for this price point. The thermal management is also adequate during prolonged use.

Perfect for Voice AI Projects
This board is exactly what I needed for my home assistant project. The integration with the Xiaozhi AI model is seamless, and the voice recognition latency is impressively low. The 1.54-inch screen is bright and clear.

Excellent value for money
Considering the included LCD, microphone, and generous memory specs, this board offers incredible value. It booted up immediately after connecting via USB-C. Highly recommended for learning embedded AI.

Good starter board for AI
As someone new to ESP32, this board made it easy to get started with voice chat applications. The pre-loaded examples worked out of the box. Only wish it came with a small battery included.

Great hardware, documentation could be better
The ESP32-S3 chip performs wonderfully with the 8MB PSRAM. I was able to run local LLM queries smoothly. However, finding specific pinout diagrams for the audio codec took some digging in the GitHub repo.

Solid build quality
The PCB feels robust and the components are well-soldered. The display colors are vibrant, and the touch response (if enabled in firmware) is accurate. Great for prototyping smart displays.
Q: Does this board support MicroPython or only Arduino IDE?
A: It supports both MicroPython and the Arduino IDE. You can also use ESP-IDF for more advanced development.
Q: How do I update the Xiaozhi AI firmware?
A: You can update the firmware via the USB-C port using the web flashing tool provided in our documentation repository or by compiling the latest source code from GitHub.
Q: What is the maximum capacity of the TF card it can support?
A: While the board has 16MB internal flash, the microSD slot typically supports cards up to 32GB, though 64GB cards often work if formatted correctly.
Q: Can I connect an external camera module to this board?
A: Yes, the ESP32-S3 has DVP interface pins exposed that allow you to connect compatible OV2640 or OV5640 camera modules.
Q: Is the 1.54-inch display touch-sensitive?
A: This specific version comes with a standard IPS LCD without touch capabilities. However, there are variant models available with capacitive touch if you check the product options.
