📡 Pico vs. Pico W: What’s the WiFi Difference?


Video: Let’s Make an Oscilloscope From a Raspberry Pi Pico and Android Phone (or Tablet).







This is a common fork in the road for Pico newcomers. The choice is simple: do you need to connect to the internet?

Feature Raspberry Pi Pico Raspberry Pi Pico W
Processor RP2040 RP2040
Wireless ❌ None ✅ Wi-Fi & Bluetooth LE
On-board LED Connected to GPIO25 Controlled via Wi-Fi Chip
Best For Offline projects, learning, robotics, HID devices IoT projects, web servers, wireless sensors, anything needing connectivity

The Pico W adds an Infineon CYW43439 chip to provide 2.4GHz Wi-Fi and Bluetooth 5.2 (Bluetooth is still in development for the SDK, but coming!). This opens up a whole new world of connected projects. But this addition comes with a small “gotcha” you need to be aware of.

Shared GPIO with WiFi Chip: Understanding the Nuances

On the original Pico, the onboard LED is directly connected to GPIO pin 25. On the Pico W, this pin (along with 23 and 24) is used to communicate with the wireless chip. This means you can’t use them for your own purposes if you’re using Wi-Fi.

This has caused some confusion. As one developer noted, “I still believe GPIO pins should have been virtualised with the introduction of the Pico W… but neither the Pico SDK nor MicroPython did that.”

What does this mean for you?

  • In MicroPython, instead of Pin(25), you should use Pin("LED") to control the onboard LED. This code will work on both the Pico and Pico W.
  • If you have a project designed for the original Pico that uses pins 23, 24, or 25, you’ll need to modify the code and wiring to use different pins if you want to run it on a Pico W with Wi-Fi enabled.

Hit a snag? It happens to all of us! Here are some common gremlins and how to squash them.

  • My Pico isn’t showing up as a drive!
    • Solution: Make sure you are holding down the BOOTSEL button before and while you plug in the USB cable. Also, double-check you’re using a data-capable USB cable, not a power-only one.
  • My code isn’t running!
    • Solution (MicroPython): Did you save your file as main.py on the Pico? The Pico automatically runs boot.py first, then main.py when it powers up. If it’s named something else, it won’t run automatically.
  • Thonny can’t connect to my Pico!
    • Solution: Make sure you’ve selected the correct interpreter in the bottom-right corner of Thonny (it should say something like “MicroPython (Raspberry Pi Pico)”). If it’s still not working, try unplugging the Pico, closing Thonny, then plugging the Pico back in without holding BOOTSEL, and then reopening Thonny.
  • My Pico W can’t connect to Wi-Fi!
    • Solution: Double, triple, and quadruple-check your Wi-Fi SSID (name) and password. They are case-sensitive! Also, ensure your Wi-Fi is a 2.4GHz network, as the Pico W does not support 5GHz networks.
