High Tech Brain
The EZ-B v4 is not only the brain of your EZ-Robot, it is also the World's most powerful and compact
robot brain! The EZ-B v4 scales for beginner and advanced users. The EZ-B is two PCB's sandwiched
together in a compact 2x2 inch package. For protection, the speaker and electronics are enclosed within
a stylish white plastic shell with a speaker chamber for clear enhanced audio. For advanced users, the
EZ-B may be removed from its casing and mounted directly in your custom robot.
