Powerful RISC-V Performance
The dual-core 400MHz processor handles complex GUI tasks without lag. I'm running a custom dashboard with real-time data plotting, and it performs smoothly. Highly recommended for advanced learners.

Ideal for Industrial Prototyping
Used this for a factory monitoring prototype. The wide voltage input and robust connectors make it suitable for noisy environments. The capacitive screen works well even with light gloves.

Exceeded Expectations
The build quality is solid. I appreciate the included screw terminals which saved me time soldering headers for my sensor array. The Wi-Fi range is also surprisingly good through walls.

Good value but steep learning curve
Amazing hardware for the price. However, if you are new to ESP32-P4, be prepared to dig into forums for library compatibility. Once set up, it's a fantastic learning tool.

Great board, minor documentation gaps
Hardware quality is top-notch as expected from Waveshare. The RS485 and CAN interfaces are very useful for industrial sensors. Would give 5 stars if the pinout diagram in the wiki was slightly more detailed for beginners.

Perfect for Smart Home HMI Projects
The 4-inch screen is crisp and the touch response is excellent. Integrating this into my home automation system was straightforward using ESP-IDF. The 86-box form factor makes it look professional on the wall.
Q: Does this board support MicroPython out of the box?
A: The board comes with a basic demo firmware. You will need to flash the MicroPython binary yourself, but the hardware is fully compatible and widely supported by the community.
Q: What is the maximum resolution supported for video playback?
A: While the screen resolution is 480x480, the ESP32-P4 can handle simple video decoding. However, it is optimized for UI rendering and static images rather than high-frame-rate video streaming.
Q: Is the LCD screen replaceable if it gets damaged?
A: Yes, the display connects via a standard FPC connector. Replacement screens are available separately in our store under the accessory section for this specific model.
Q: Can I power this directly from a 24V industrial supply?
A: No, the onboard regulator accepts 5V input via USB-C or the terminal block. For 24V systems, please use an external buck converter to step down to 5V before connecting to the board.
Q: Are there example projects for connecting Modbus devices?
A: Yes, our GitHub repository contains several examples demonstrating Modbus RTU communication over the RS485 interface specifically for this Smart 86-Box model.
