ERROR 'Serial5' was not declared in this scope

Hi, I followed http://misfittech.net/blog/arduino-package-install/ and have a MKS SERVO42A, I bought it without knowing the story about this copy-product, but I need to buy some others soon for my bachelor project. I'm trying the .ino in this hub, the last version but I got this error:

I really, really hope for help. @trampas @Misfittech Have a great day!

Please post your board.h file

I hope you found a workaround but am posting in case anyone else is looking back at this.

I encountered this same error when I selected the wrong board. Be sure to install and select the correct board in the Arduino Boards Manager. The name should be MisfitTech SAMD Boards in the Boards Manager. When skimming the instructions it was easy for me to mistakenly select the "Arduino Zero" board instead of the intended Nano Zero board.
