1.1. Configurations and included components

The 3pi+ 2040 robot is available as a kit or fully assembled with three different motor options:

In addition, the 3pi+ chassis and 3pi+ 2040 control board are available separately and can be combined with the motors of your choice to make a custom kit.

A version of the 3pi+ robot based on the Arduino-compatible ATmega32U4 MCU is also available. See the 3pi+ 32U4 OLED Robot for more information.
