<![CDATA[T-RGB (Round) - Available GPIO Ports]]>I am looking to use the T-RGB display on a project to display the water level of 4 tanks. I haven't chosen the senders yet, but are likely to be simple resistive type senders. Are there any available GPIO ports or are they all taken up with the display?

That was the conclusion I was coming to. Realistically, I can only use i2c, rather than some resistive sensors and use some A2D pins.

https://github.com/Xinyuan-LilyGO/T-RGB
It matters what senders you are using, could you be more specific?
There is only one Grove port and beware that the pins are not standard qwiic or M5Stack wire position correct.
So with only 2 GPIO avail, and you would have to make your own cable to correct the pin order, you may have to go the i2c route with an i2c I/o expander. Not very neat!
