Possible to connect more tan one 4-20mA module via I2C (DFR0972)?
Manney.Kerkkamp 2025-02-18 19:54:59 454 Views2 Replies For a project I need 3 analog outputs 4-20mA but on the documentation af the DFR0972 I only see one I2C adress.
Is it possible to control more than one unit via the same I2C bus?

If you want to use three DFR0972 at the same time, we recommend purchasing one DFR0759 (I2C HUB) to implement your idea. DFR0759:重力：I2C HUB Arduino - DFRobot --- Gravity: I2C HUB Arduino - DFRobot

The DF09872 all have the same address, so a simple hub will not work. Can individual addresses be changed.
