Quality: The product is really good, the materials are abundant, and the board is excellent. The customer service attitude is also very good. The Orin Nano has quite a big change in appearance compared to the Nano. I followed the tutorial to operate it, and when I had questions about the tutorial that I didn’t understand, I consulted the technical support, and all problems were finally solved. Next, I need to start secondary development by myself. For beginners, the reference value of the merchant’s materials is quite high.
