Missing USB cable
The board itself is fine, but my kit arrived without the USB programming cable. I had to buy one separately which was inconvenient.

Integrated easily with my existing HarmonyOS ecosystem. The GPIO pins are well labeled and easy to use for beginners.

Good hardware, docs need update
The board works well and feels sturdy. However, some of the software examples were outdated. Once I found the latest SDK, everything worked fine.
