The 3pi+ 2040 Control Board is designed to be assembled with a 3pi+ Chassis Kit, a pair of 6V Micro Metal Gearmotors with extended motor shafts, and a graphical OLED display to create a 3pi+ 2040 robot. This product is primarily intended as a replacement product for the 3pi+ 2040 robots and kits that already include it or for those who want to build a 3pi+ 2040 robot with different gearmotor versions than the ones offered with those complete kits and assembled robots.

This control board is already included as part of the following 3pi+ 2040 assembled robots and kits:

Included components

The 3pi+ 2040 Control Board ships with all of its surface-mount components populated, and it includes the following through-hole parts and mounting hardware:

one buzzer
jumper wires for soldering motors to the board
two magnetic encoder discs
one low-profile 1×7 male header for use with a graphical OLED display (not included)
four single battery contacts
four 3/16" #2-56 screws, two 1/4" #2-56 standoffs, and four nuts for mounting the board to a 3pi+ Chassis and an OLED display to the board

Please note that assembly (including soldering) is required; see the user’s guide for assembly instructions.

What else you will need

To build a robot with the 3pi+ 2040 Control Board, you will need a few additional parts:

a 3pi+ Chassis Kit
two Micro Metal Gearmotors with extended motor shafts (6V MP or 6V HPCB versions recommended)
a graphical OLED display (this is not required for operation, but it is strongly recommended)
four AAA batteries: the 3pi+ chassis and control board work with both alkaline and NiMH batteries, though Pololu recommend rechargeable NiMH cells
a USB A to Micro-B cable to connect the robot to your computer for programming and debugging
tools to help with kit assembly; see the user’s guide for a list of specific tools

Optional accessories

You might also consider getting these for your 3pi+ 2040 robot:

more sensors
connectors (headers, jumper wires, etc) for adding those sensors or other peripherals to the 3pi+ 2040 expansion ports
