If every keybit is the same way round any shape works, like a square with the keyword in one corner. 3V on its SCL and GND on its SDA, so it gets no power and nothing behind it shows up until it's turned.

This project contains an open source low-cost, easy-to-build motorized XYZ Micro-Manipulator motion control platform achieving submicron precision. It's designed for applications such as optical alignment, probing electronic components, and microscopy.
