multiple 4-Relays on same I2C bus
-
Is there a way to control more then 1 4-relay units with a StickC+ ?

Hello @bartblommaerts
from what I can tell the 4-relay unit has a fixed I2C address (0x26) so connecting more than one directly doesn't work (I2C address conflict).
However you should be able to control multiple 4-Relay units through a PaHub2.
Note: I do not have the necessary units to test whether it actually works or not. My conclusion is solely from looking at the documentation.
Thanks

Felix@felmue is correct. The Address is hard coded and so you need to use the I2C hub for more that 1 unit.

Oh the PaHub>2< Unit :/
its not available yet in the local stores. And the Pa.Hub (version 1) is sold out.

You're better off ordering direct from M5Stack
