Change I2C SDA and SCL pin of Arduino and Trinket M0

[TomGeorge]

Hi, @ak474849
Welcome to the froum.

@ak474849

So, when one Trinket M0 communicates with sensor, the other trinket boards cannot communicate with the sensor to their peripheral and I don't want this to happen. That's the reason I need separate SDA and SCL for Arduino to trinket M0.

Are you aware that I2C consists of basically a master controller and slaves?

What ever controller you use as the master, even with more than one I2C bus, it can only communicate with one I2C bus at a time.

Having one I2C bus will not have crashes as the master will be addressing each slave on the I2C bus in turn.
If the Trinkets all get readings from the same Uno, then you will have to make the UNO the master and each Trinket the slave.

What is your application, what data is being collected by the UNO and disseminated to each Trinket?
How long is the I2C link (cm)?
What does each Trinket do with the data it receives?
