This little number is an interface board for any BS2-compatible or Stamp Stack II controller, it is intended for use with products that were designed to accept Solarbotics add-on brainboards such as the Sumovore and ScoutWalker III.
The Solarbotics Sumovore Kit is a strong, modular design with over 500 man-hours of development and 21 prototypes behind it. It has more power, speed, and is less expensive than the Junun Mark III, Parallax Mini-Sumo, and Tab SumoBot.
This is Sparkfun's latest evolution of serial LCD. On-board is a 16x2 character LCD with an embedded circuit based around the PIC16F88. Via a TTL-serial interface you can issue commands to display characters, clear the screen, adjust the backlight brightness, turn the display on/off, and more!
