The Pololu 3pi robot is a complete, high-performance mobile platform featuring two micro metal gearmotors, five reflectance sensors, an 8×2 character LCD, a buzzer, and three user pushbuttons, all connected to a C-programmable ATmega168 microcontroller. Capable of speeds exceeding 3 feet per second, 3pi is a great first robot for ambitious beginners and a perfect second robot for those looking to move up from non-programmable or slower beginner robots.
This kit gives you everything you need to add a second level to your 3pi robot. The black printed circuit board matches the color of the 3pi and has cutouts that let you view the LCD below and make it easier to reach the power button, reset button, and programming header.
This kit includes a round printed circuit board (PCB) with holes spaced on a 0.100" grid, one extended 2×7 male header, two extended 2×1 male headers, a 2×7 female header, two 2×1 female headers, four 7/8" nylon spacers, four 1-1/4" screws, and four nuts.
