3pi+ 2040 Robot with 30:1 MP Motors (Standard Edition)

The Pololu 3pi+ 2040 robot is a palm-sized, high-performance mobile platform based on the Raspberry Pi RP2040 MCU, and this kit contains all the parts you need to build the Standard Edition version, including a pair of 30:1 MP 6V Micro Metal Gearmotors. The many features of the 3pi+ include dual quadrature encoders for closed-loop speed or position control, line sensors, front bump sensors, a full IMU (3-axis accelerometer, magnetometer, and gyro), six RGB LEDs, and a graphical OLED display.

Overview
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+ 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 128×64 graphical OLED display, buzzer, and six RGB LEDs allow the robot to provide feedback.
