I'm using multiple i2c, Wire and Wire1 in the due board.
In my case, I removed the internal pullup resistors, so I thought Wire and Wire are technically same.
But, Wire is not unstable than Wire1 which means I can connect 4 slaves in Wire1 while 1 slave in Wire.

Are there other difference between those two?

No, there are no differences except that SDA/SCL have pull-ups whereas SDA1/SCL1 don't have pull-ups.
