Excellent for learning AI interactions
Bought this to experiment with local AI voice commands. The microphone array integration works well, and the screen provides great visual feedback. Waveshare's examples got me started in minutes.

Solid hardware, documentation could be deeper
Hardware build quality is top-notch. The connectors are robust for industrial use. I wished there were more advanced examples for the CSI camera interface, but the community is filling the gaps quickly.

Impressive performance per dollar
The dual-core performance is noticeable when running complex UI logic alongside WiFi tasks. The form factor fits perfectly into standard enclosure boxes. Very happy with this purchase for our prototype phase.

Best value touchscreen dev board
I've used several ESP32 boards, but the P4 with this specific 86-box display is a game changer. The square resolution is unique and perfect for dashboard interfaces. Compilation times are fast too.

Powerful but needs good power supply
This board packs a lot of power for the price. The 400MHz processor handles graphics smoothly. Just ensure you use a stable 5V source as it can be hungry under full load. Otherwise, highly recommended.
Q: Does this board support external cameras via the CSI interface?
A: Yes, the ESP32-P4 on this board features a MIPI CSI interface that supports connecting compatible camera modules for image processing tasks.
Q: Is the XiaoZhi AI feature cloud-dependent or does it run locally?
A: The basic voice recognition and interaction features can run locally on the device, though some advanced natural language processing capabilities may utilize cloud APIs depending on your configuration.
Q: Can I power this directly from a 3.7V LiPo battery?
A: No, this board requires a stable 5V input. You should use a boost converter if you plan to power it from a single-cell LiPo battery.
Q: Are there GPIO pins available for expanding sensors?
A: Yes, the board breaks out numerous GPIO pins along the edges, allowing you to connect various sensors, actuators, and communication modules like RS485 for industrial control.
Q: What is the brightness level of the screen for outdoor use?
A: The display has a typical brightness of 500 nits, which makes it readable in indoor environments and shaded outdoor areas, but direct sunlight may still reduce visibility.
