Excellent value for money
For the price, you cannot beat this kit. It supports standard protocols like MQTT out of the box with the right SDK. Shipping was fast and the packaging protected the components well.

Good but needs better examples
The board itself works fine, but I wish there were more English code examples included for specific sensors. I had to search online forums to get my temperature sensor working correctly.

Great hardware, steep learning curve
The Hi3861 chip is powerful for its size. However, if you are used to Arduino, the toolchain setup takes some time. Once configured, the performance is excellent for small sensor projects.

Solid build quality
I bought three of these for a university project. All three worked flawlessly. The USB interface makes debugging very convenient compared to other boards that require external programmers.

Works as advertised
I successfully flashed my first Hello World application within an hour. The pinout is clearly marked on the board, which helps prevent wiring mistakes. Recommended for intermediate users.

Perfect for HarmonyOS Beginners
This board is exactly what I needed to start learning HarmonyOS IoT development. The documentation provided by the seller was helpful, and the board connected to my Wi-Fi network without any issues on the first try.
Q: Does this board support Python programming?
A: The Hi3861 primarily supports C/C++ development using the HarmonyOS SDK. While MicroPython ports exist for some HiSilicon chips, official support for this specific board focuses on C-based development.
Q: Is an external antenna required for Wi-Fi?
A: No, this board comes with a built-in PCB antenna that works well for most indoor applications. There is a connector for an external antenna if you need extended range.
Q: What voltage should I apply to the VIN pin?
A: Please supply 3.3V DC to the power pins. Applying higher voltages directly to the logic pins may damage the board. The USB port provides regulated power safely.
Q: Does the kit include a USB cable?
A: Yes, the kit includes a micro-USB cable for both power supply and serial communication/programming. No additional cables are needed to get started.
Q: Can I use this with the Arduino IDE?
A: This board is not natively supported by the standard Arduino IDE. You will need to use the DevEco Studio or the specific Hi3861 toolchain provided in the HarmonyOS ecosystem.
