Welcome to Pico Robot Car repository

1.1 Introduction to Pico Robot

Currently, Pico Robot has two optional main controllers, Pico and Pico 2. Pico Robot is an open source robot that can be used by embedded designers, researchers and students. The robot comes with ultrasonic and photosensitive sensors, OLED and infrared receivers, which can quickly achieve obstacle avoidance, remote control and other functions.

Raspberry Pi Pico is a low-cost, high-performance microcontroller development board designed by Raspberry Pi with flexible digital interface. In terms of hardware, it uses the RP2040 microcontroller chip independently developed by Raspberry Pi, equipped with an ARM Cortex M0 + dual-core processor with an operating frequency of up to 133MHz, built-in 264KB SRAM and 2MB memory, and up to 26 multi-function GPIO pins on board. In terms of software, MicroPython can be used for development, and it is equipped with a complete development material tutorial, which can facilitate quick entry and development, and embed the application into the product.

Raspberry Pi Pico 2 is also a low-cost, high-performance microcontroller development board designed by Raspberry Pi. However, it is different from Pico in hardware. It uses the RP2350 microcontroller chip independently developed by Raspberry Pi, equipped with dual ARM Cortex M33 or Hazard3 processors, up to 150MHz operating frequency, built-in 520KB SRAM and 4MB memory.
