I mistakenly connected it wrong. It functions as a I2C keyb out of the box. I flashed it w/ the Arduino IDE to be a UART serial keyboad (i.e. terminal). Great! :)

CardKB as I2C keaybord on R. Pi
I'd like to use the CardKB as an I2C device on a Raspberry Pi (link for Pi setup).
However, the following command produces no address for the keyboard and it does not work. Do I have to flash firmware to it? This is my 2nd CardKB because I broke the first one trying to flask firmware to it w/ the Arduino IDE.
i2cdetect -y 1
I don't get it. Why won't it work? Is my CardKB broken?
