Introduction to EDU PICO V2

What is EDU PICO V2?

EDU PICO V2 is an all-in-one learning tool that can help you learn how to build electronic projects using the Raspberry Pi Pico 2 W microcontroller. It's a special board that comes with all sensors preconnected to help you learn more seamlessly. This means that you can start experimenting and building things right away, without needing to know a lot about electronics.

Introduction to Thonny IDE

What You Need?

Step 1:

Connect the EDU PICO V2 to your computer's USB port.

Raspberry Pi Pico 2 W microcontroller
EDU PICO 2 board
Micro B USB cable
Computer (Laptop / Desktop)

Step 2:

Flip the ON/OFF switch (downwards) to turn it ‘ON’.

Step 3:

Download and install ‘Thonny IDE’ on your computer.

Step 4:

Launch Thonny IDE and select ‘CircuitPython (generic)’ as the interpreter.

Step 5:

Let’s configure Thonny IDE’s theme and font so that it matches the guidebook’s theme. This will make sure you can go through the guidebook smoothly later.

Select Tools > Options > Theme & Font. Follow the settings below for UI theme, Syntax theme, Editor font and IO font.

Step 6: Select ‘OK’, and restart Thonny IDE to make sure the style elements take effect.

Now you’re all set for your first program!

Preparing EDU PICO CircuitPython Firmware

Step 1:

Launch Thonny IDE and make sure your computer has internet connection.

Step 2:

Press and hold the reset (RST) and BOOTSEL buttons, then release the RST button, but continue to hold the BOOTSEL button until the RP2350 drive appears.

Step 3:

Click on the bar at the bottom right corner and select Install CircuitPython from the drop-down menu.

Step 4:

Select RP2350 for the target volume, and Cytron Technologies - EDU PICO 2 for Pico 2 W for the variant. Then select the latest stable version and Click Install.

Step 5:

Wait for the download and installation to be done. Close all pop-up windows.

Step 6:

After successful installation, the CircuitPython drive will appear on your computer. Click the bottom right corner of Thonny and select the CircuitPython option as shown.
