at90usb1287 teensylu

Hello everybody

i am new to this forum and to 3d printing
i wont to make a 3d printer based on the teensylu electronics but the problem is that where i live we don't have the AT90USB1286

i can only found the AT90USB1287

can i use the 1287 mcu instead of 1286 mcu ?? if yes should i do anything other than the instructions in the teensylu page to upload the repetier firmware ??

should i do anything related to the fuses settings (because i got confused when i read about fuses)

sorry about my bad English

hope anybody can help me

According to the Teensylu wiki page:

Teensylu clone, Atmel's AT90USB1286 - AT90USB1287 drop-in compatible for 20mhz support

So they are interchangeable. A little more digging and it looks like main difference is that the 1287 supports USB Host mode and not just a device, but that isn't necessary for our normal use.

thank you so much cdru you helped me a lot
