Mark III Controller Board Kit


Click for larger image
Controller board for Mark III. Just the electronics. Includes all the parts needed including PIC preprogrammed with the bootloader. Buy this item if you already have a robot base, motors, and sensors - this is just the "brains". Can also be used as a general-purpose PIC development board. Assembly required.

Picture shown is of a prototype - actual Controller board will have several small differences. A new photo will be posted when available.
