Raspberry Pi Pico W is a new microcontroller board made by the popular Raspberry Pi single-board computer makers. The device has 2.4GHz 802.11 b/g/n wireless LAN support. It has an onboard antenna.
It has an onboard antenna. the unique chip of this device supports both station and access-point modes. Moreover, however, in the broadcast of this device, Full access to network functionality is available to both C and MicroPython developers.
Bluetooth is not enabled on Raspberry Pi Pico W. This is due to software limitations(SDK) and not hardware.
RP2040 chips and a power supply chip are available in 2MB of flash memory. it can support input voltages from 1.8–5.5V. Moreover, they provide 26 GPIO pins, three of which can function as analogue inputs, on 0.1”-pitch through-hole pads with castellated edges.

Programming & Installing MicroPython on Raspberry Pi Pico W
The Raspberry Pi Pico W can be programmed using C/C++ or MicroPython, among other languages. The Pico W is suitable for a wide range of applications and skill levels, and getting started is as simple as dragging and dropping a file. If you are developing in C, it is advisable to use a Linux-based system, such as a Raspberry Pi computer, as it makes downloading the SDK and writing C programs easier.
For programming the Raspberry Pi Pico W board, I recommend using MicroPython. MicroPython is a Python interpreter designed for microcontrollers and embedded systems. MicroPython’s syntax is quite similar to Python’s, so if you’ve worked with Python before, you’ll find working with MicroPython very straightforward.
However, before you can start using the Raspberry Pi Pico W, you must first install MicroPython on the board.
Push and hold the Pico W’s BOOTSEL button, then instantly connect the Pico W Board to your computer via a micro USB cable. Once the RPI-RP2 drive shows on your computer, release BOOTSEL.
Open the RPI-RP2 drive that appears in the Drives tab.
Visit the Raspberry Pi Pico W Official Documentation page from here: Raspberry Pi Datasheets.
Download the MicroPython UF2 file from the MicroPython tab.
Drag and drop the UF2 file onto the RPI-RP2 drive. The Raspberry Pi Pico W will reboot and will now run MicroPython.
Now you can start using the Raspberry Pi Pico W with MicroPython on Thonny IDE & make unlimited IoT projects.
Getting Started with Raspberry Pi Pico W using MicroPython
Now let us get started with Raspberry Pi Pico W using MicroPython on Thonny IDE. First you have to download Thonny from the https://thonny.org/
Connect the Raspberry Pi Pico W to your computer. Then from Thonny go to Tools > Options and click on the Interpreter tab. From the interpreter dropdown list, select MicroPython (Raspberry Pi Pico). The port dropdown menu can be left to automatically detect the Pico. Click Ok to close.
After a successful connection, the MicroPython version and Raspberry board will appear in the Python Shell. To test we can write a quick print function to say “Hello World”. Press Enter to run the code. You will get Hello World as a response.
You can also check the device information by following commands.
The directory can also be viewed using the following command.
Scanning WiFi Access Points
The Raspberry Pi Pico W has CYW43439 2.4-GHz Wi-Fi chip from Infineon. So the Board can connect to the WiFi network and all the features related to WiFi can be accessed as well.
Lets scan all the available Network Access Points using the Raspberry Pi Pico W working in a station Mode.
In the Thonny editor, paste the following code and save it with any name like main.py.
Now hit the run button to run the code.
The WiFi chip will scan all the available network and shows the list of all the network in Shell Window.
Connecting to the Internet (WLAN/WiFi Network)
Now let’s see how Raspberry Pi Pico W connects to the Wi-Fi network.
Create a new script by clicking the New button on Thonny IDE. Copy and paste the following code. Replace the WiFi credentials by changing the SSID and PASSWORD to your own.
Now Run current script. If the connection is successful, true will be printed.
Timeout Judgment & Showing Raspberry Pi Pico W IP Address
Considering some poor network conditions, let’s add some timeout judgment to the code and also print the IP Address of the network to which the Pico W get connected.
Create a new script by clicking the New button on Thonny IDE. Copy and paste the following code. Replace the WiFi credentials.
Now run the script.
The Thonny Shell will display the IP Address of the Pico W.
wlan.status()function: Returns the current status of the wireless connectionwlan.ifconfig()function: Obtains IP addresses, subnet masks, gateways, and DNS servers. This method will return a 4-tuple containing the above information when called directly. In this case, we only print the IP address.
For more information about the WiFi commands, refer to the class WLAN MicroPython documentation.
Storing WiFi Credentials on Secret File & Simplify WiFi Connection
When you share your Pico W project, you should not want others to see your Wi-Fi password or API key. For good security, we can create a secrets.py file to store your private information.
Considering that each of our next projects will require a network connection, why don’t we create a new do_connect.py file and write the relevant functions into it for reuse, which can greatly streamline the code of complex projects.
secrets.py
Copy the following code into a new script file on Thonny. Note to change SSID and PASSWORD to yours. Set the file name to secrets.py
do_connect.py
Copy the following code into a new script file, and save it to Raspberry Pi Pico as do_connect.py.
main.py
Calling the above script in other scripts by the following will allow the Raspberry Pi Pico W to connect to the network.
After running all the 3 scripts, the Pico W will connect to the WiFi Network.
