Attach two servos to the top plate, great for robot arms
Mount a second Raspberry Pi (Zero or 3) for extra processing power
Mount an Arduino Uno (or similar) to tackle sensor processing tasks
Fit more sensors and hardware using extra holes
This kit comes with additional posts so that the Multifunction Top can be fitted as an extra tier above or below the display top. Alternatively you can keep the low profile and simply replace the standard Display Top instead.
