Great hardware, steep learning curve
The hardware quality is excellent for the price. However, if you are new to the Hongmeng ecosystem, expect to spend some time reading docs. Once configured, the Wi-Fi stability is impressive.

Best value RISC-V board available
Compared to other development boards in this category, the BearPi-HM_Nano offers unbeatable value. The community support is growing fast, and there are plenty of sample codes available.

Solid performance for smart home prototypes
Used this to build a smart temperature sensor. The connection to the cloud via OpenHarmony was smooth. Only minor issue was the initial driver installation on Windows, but support helped quickly.

Perfect for OpenHarmony Beginners
This board is exactly what I needed to start learning OpenHarmony. The documentation is clear, and the Hi3861 chip performs reliably for IoT projects. Setup was straightforward using the DevEco Studio.

Good board, limited advanced docs
The board works well for basic tasks. However, finding detailed technical references for advanced peripheral configuration was a bit difficult. Still, it's a good entry point for the ecosystem.

Ideal for classroom use
We bought ten of these for our university lab. Students find them easy to program, and the small form factor fits well on breadboards. Highly recommended for educational purposes.
Q: How do I reset the board if it freezes?
A: You can perform a hard reset by pressing the RST button located next to the USB port, or simply disconnect and reconnect the power supply.
Q: Does this board support Python programming?
A: Yes, the BearPi-HM_Nano supports MicroPython through the OpenHarmony framework, allowing you to write scripts directly on the device.
Q: Is there a camera interface available on this nano version?
A: No, the BearPi-HM_Nano model does not have a dedicated camera interface due to its compact size and pin limitations. Please consider the BearPi-HM_Pro if you require camera capabilities.
Q: Can I power this board with a 5V USB cable?
A: Yes, the board includes an onboard LDO regulator that accepts 5V input via the standard USB Type-C port and converts it to the required 3.3V for the chip.
Q: What IDE should I use for development?
A: We recommend using DevEco Studio, which is the official integrated development environment for OpenHarmony applications and provides full debugging support for the Hi3861 chip.
