3pi 2040 Robot - Turtle Edition (75:1 LP Motors), Assembled
The Pololu 3pi 2040 robot is a palm-sized, high-performance mobile platform based on the Raspberry Pi RP2040 MCU. It includes dual quadrature encoders, line sensors, front bump sensors, a full IMU (3-axis accelerometer, magnetometer, and gyro), six RGB LEDs, and a graphical OLED display. The Turtle Edition version features 75:1 LP 6V Micro Metal Gearmotors, offering longer battery life and a maximum speed of 0.4 m/s, making it ideal for controlled-speed applications.
Overview
The 3pi 2040 is a high-performance, user-programmable robot measuring 9.7 cm in diameter. Powered by a Raspberry Pi RP2040 microcontroller, a 32-bit dual-core Arm Cortex-M0 processor running at 125 MHz, it supports programming in C, C , Arduino, and Python. The 3pi 2040 has 16 MB of flash memory preloaded with MicroPython, allowing users to start programming immediately via the USB-C port.
