The Pololu 3pi+ 2040 robot is a high-performance mobile platform based on the Raspberry Pi RP2040 MCU. Its many features include dual quadrature encoders for closed-loop speed/position control, line sensors, front bump sensors, a full IMU (3-axis accelerometer, magnetometer, and gyro), and a graphical OLED display. This Hyper Edition version is assembled with high-speed 15:1 HPCB 6V Micro Metal Gearmotors.
NOTE: This version is difficult to control and fast enough to damage itself from impacts, so it is only recommended for advanced users. A spare 15:1 gearbox is included.
The 3pi+ 2040 is a versatile, high-performance, user-programmable robot that measures just 9.7 cm (3.8?) in diameter. At its heart is a Raspberry Pi RP2040 microcontroller (like the one on the Raspberry Pi Pico), a 32-bit dual-core Arm Cortex-M0+ processor running at 125 MHz, which can be programmed with C, C++, Arduino, or Python. The 3pi+ 2040 has 16 MB (128 Mbit) of flash memory that ships preloaded with a MicroPython interpreter, so you can get started right away by plugging into its USB C port and editing the included example Python programs. For advanced users who want to customize or enhance their robots with additional peripherals, the robot’s power rails, power system controls, and microcontroller’s I/O lines can be accessed via several 0.1?-pitch expansion ports.
The 3pi+ (or 3??+) 2040 features two H-bridge motor drivers and a variety of integrated sensors, including a pair of quadrature encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyro, and magnetometer), five downward-facing reflectance sensors for line-following or edge-detection, and left and right bump sensors along the front face of the robot. Three on-board pushbuttons offer a convenient interface for user input, and a 128x64 graphical OLED display, buzzer, and six RGB LEDs allow the robot to provide feedback.
What else you will need
- four AAA batteries: the 3pi+ robot works with both alkaline and NiMH batteries, though we recommend rechargeable NiMH cells
- a USB C cable to connect the robot to your computer for programming and debugging
This product is the assembled Hyper Edition of the 3pi+ 32U4 OLED Robot. It is very difficult to control and fast enough to damage itself from impacts, so it is only recommended for advanced users. We strongly recommend keeping motor speeds below 50% on this version. A spare gearbox is included with this edition and instructions for installing it can be found here (note that this video was made for an older version of the 3pi+ robot, but the mechanical instructions for replacing the gearbox still apply to this newer 2040 version).
