The m3pi expansion kit gives 3pi robot users a convenient way to upgrade the functionality of their robots by adding more features, enabling the use of more capable high-level controllers like an mbed development board, and making it easy to integrate wireless modules like an XBee or Wixel (MCM Part# 28-17702).
This kit is also available fully-assembled with a 3pi robot (MCM Part# 28-17627).
The kit includes an expansion PCB with all of the surface-mount parts populated. Assembly of the kit requires the included headers and pushbuttons to be soldered to the PCB. Once assembled and connected to a 3pi robot (not included), you will have your own m3pi robot.
