<![CDATA[Additional I2C device on pytrack]]>One of my Lopy's is connected to an expensionboard. It was possible for me to connect a SSD1306 OLED to view some data while not connected to my computer.

For my other Lopy connected to a Pytrack i can't find the way how to connect another device to the ic2 ports via de external io-ports. What is the proper way to accomplish this?

You may use these for an I2C display

However, i already did use P9 en P10 for buttons. I'm using the pytrack for a movable cache (geocaching) and need some more user interaction than - probably - normaly would be used with an iot-device.
