Hi RongZhong,
It's the board shipped with the Bittle, NyBoard V0_1 according to the print on the board. I also downloaded the Adafruit Servo file that caused an earlier error before this one popped-up.
As mentioned, I tend to get things working even when having to Google-translate Chinese websites but am pretty much stuck on this one. She is working off an Apple in case that makes a difference, frankly the system I am least familiar with.
Regards,
Jeroen
