The Pico-4wd is a Raspberry Pi Pico based, cool, robot car kit that everyone can have.
Equipped with greyscale sensor module and ultrasonic module, it can perform line tracking, cliff detection, follow and
obstacle avoidance functions. The RGB boards assembled at the bottom and rear of the car make it the coolest spirit
in the dark.
We have provided sample code based on MicroPython so you can get started quickly.
In addition, you can also use an app - SunFounder Controller - to DIY your own control methods! Let’s Play!

CHAPTER
ONE
GET STARTED
In this section, you will learn all the hardware and software configurations needed to get Pico-4wd up and running,
and it is recommended that you read them in order.
1.1 1. Install Thonny IDE
Before you can start to program Pico with MicroPython, you need an integrated development environment (IDE), here
we recommend Thonny. Thonny comes with Python 3.7 built in, just one simple installer is needed and you’re ready
to learn programming.
Note: Since the Raspberry Pi Pico interpreter only works with Thonny version 3.3.3 or later, you can skip this chapter
if you have it; otherwise, please update or install it.
1. You can download it by visiting the website. Once open the page, you will see a light gray box in the upper right
corner, click on the link that applies to your operating system.
2. The installers have been signed with a new certificate which hasn’t built up its reputation yet. You may need
to click through your browser warning (e.g. choose “Keep” instead of “Discard” in Chrome) and Windows
Defender warning (More info Run anyway).
