The file you are downloading is a UF2 boot file, when mounted into the boot folder on the Pico it will start and load CircuitPython. Let’s do that now. Reset and BOOTSEL In order to open up the Pico as a drive, you need to hold down the BOOTSEL key while plugging in the Pico...

WAV files are easiest for CircuitPython to play. The shortest code to play a WAV file on Pico RP2040 is:import time, board, audiocore, audiopwmio audio = audiopwmio.PWMAudioOut(board.GP0) wave = audiocore.WaveFile("laser2.wav") audio.play(wave) while True: pass # wait for audio ...

I then opened Thonny to run the sample provided by Cytron, and I had to change the Interpreter to CircuitPython (generic) and select the port “Pico -CircuitPython CDC control (/dev/ttyACM0). Here’s the source code to create a text file on the SD card and write some text in CircuitP...
This project is an OBS Controller using a Raspberry Pi Pico and CircuitPython. It's alive! The Pico Producer (new name) is assembled! 12 buttons and LEDs hooked up to a@Raspberry_Pi#RaspberryPiPicoacting as a HID device using Circuit Python!

That means the Maker Nano RP2040 board comes pre-installed with CircuitPython, so we can use the board out of the box! But if you wanted to install the latest version of the firmware, you could do so using the samefirmware update method as for Raspberry Pi Pico. ...
