1.1. Configurations and included components

The 3pi+ 32U4 OLED robot is available as a kit or fully assembled with three different motor options:

3pi+ 32U4 OLED Version	Products	Micro Metal Gearmotor	Top Speed	Comments
Standard Edition	assembled or kit	30:1 MP 6V	1.5 m/s	good combination of speed and controllability
Turtle Edition	assembled or kit	75:1 LP 6V	0.4 m/s	longest battery life, easiest to control, good for swarm robots or introductory robotics courses
Hyper Edition	assembled or kit	15:1 HPCB 6V	~4 m/s	very fast and difficult to control, easy to damage; only recommended for advanced users

In addition, the 3pi+ chassis and 3pi+ 32U4 OLED control board are available separately and can be combined with the motors of your choice to make a custom kit.

The original (LCD) version of the 3pi+ 32U4 robot is also available in these three editions—Standard (assembled or kit), Turtle (assembled or kit), and Hyper (assembled or kit)—and as a separate control board.

  • buzzer
  • jumper wires (for soldering motors to the main board)
  • 1×7 low-profile male header for OLED display (original version kits include an 2×7 low-profile male header for the LCD instead)
  • two magnetic encoder discs (12 CPR)
  • four 3/16″ #2-56 screws and nuts

• graphical OLED display (original version kits include an 8×2 character LCD instead)
• spare 15:1 gearbox (Hyper Edition only)

The robot and chassis kit might include extra parts like jumper wires, screws, and nuts, so do not be concerned if you have some leftover hardware after assembling your 3pi+.

Assembled 3pi+ 32U4 robot

The assembled versions of the 3pi+ 32U4 robot are complete, ready-to-program robot platforms built from the same components found in the 3pi+ 32U4 robot kits; no soldering or assembly is required.
