2 Gesture Boards on an UNO???

Projects General Guidance
1

I have an application where I would like to use an UNO and 2 Gesture boards. I am using a Gravitech I2CPROX board. The board seems to work great, BUT the I2C address is had coded. That is I cannot change the address. This means I cannot daisy chain 2 boards on the same I2C port on the Arduino. My understanding is that there is only 1 usable I2C port on the UNO. BUMMER!
Does anyone know of a "trick" I can use to have the UNO support 2 I2C devices with the same address? I am open to any and all ideas :slight_smile:

thanks!!

Use an I2C multiplexer.
