I2C 8 Channel relay board

Does anyone have a design for an 8 channel relay board with an I2C interface with selectable I2C address?

I would have thought this was common place but I can’t seem to find any designs.


A google search for “fritzing part i2c 8 channel relay board” turns up


if you are looking to make one from components. A google search for “i2c 8 channel relay board” turns up a bunch of modules (which may or may not have Fritzing parts) if you are looking for a prebuilt module.


Hi chomski99,

yes, i have find the same on the fritzing website as vanepp has find.

But normaly, this is not really very difficould. You should design an self-one.
