I2C - is this the right place?

Post by SkyRyder »

Hi all, is I2c part of Adafruit IO? Is this the forum to discuss I2C?

If so, I would like to set up a 1 channel relay module with I2C. I can't find one in the Adafruit product listings... help!

Thank you

AdafruitIO is our online platform. It doesn’t interact with component-level protocols like I2C.

We don’t carry any relays with a I2C interface. We have relay FeatherWings that can be triggered with a GPIO pin:

You could probably connect one to an I2C GPIO expander like the MCP23008:

The Seesaw GPIO expander uses I2C and has digital pins:

It can't handle enough current for a relay by itself though. You'll still need something like a mosfet to control the actual relay coil.
