THREE SIMPLE STEPS
How to use the Raspberry Pi Pico Simulator
Wire LEDs and buttons
Add parts and choose their GPIO pins. Pins light up on the board as your code drives them.
Press Run
Watch the LEDs, press buttons and read the output in the REPL console, as on a real Pico.

Raspberry Pi Pico Simulator FAQ
Is the Raspberry Pi Pico simulator free?
Yes. No account, no time limit and nothing to install: it runs in your browser.
Does it run real Pico firmware?
Yes. It boots the official MicroPython build for the Raspberry Pi Pico, unchanged, and can run your own RP2040 .uf2 or .bin files.
Do I need a Raspberry Pi Pico?
No. The board, its GPIO pins, LEDs, buttons and knobs are simulated in your browser. When your code works, copy it to a real board.
Can I use the MicroPython REPL?
Yes. Type into the REPL console while your code runs, just as over USB serial on a real Pico, and save your code as main.py on the simulated board.
Is it affiliated with Raspberry Pi?
No. It's an independent simulator; Raspberry Pi and Pico are trademarks of Raspberry Pi Ltd.
