The Short Answer

Does Raspberry Pi Pico Have Wifi? The standard Raspberry Pi Pico does not have WiFi. It is a capable microcontroller board built around the RP2040 chip, but it has no wireless radio. However, the Raspberry Pi Pico W, released later, does include WiFi and Bluetooth support. So the accurate answer depends on which board you own or plan to buy.

If your project requires network connectivity, choose the Raspberry Pi Pico W. If you already own the original Pico, you can still add wireless capability using an external module, which we will cover later in this article.

What Is the Raspberry Pi Pico?

The Raspberry Pi Pico is a low-cost, high-performance microcontroller board introduced by the Raspberry Pi Foundation. Unlike the full-size Raspberry Pi computers, which run a complete operating system, the Pico is designed for embedded applications. It features the RP2040 microcontroller, a dual-core Arm Cortex-M0+ processor running at up to 133 MHz.

The board includes 264 KB of SRAM, 2 MB of onboard flash memory, and a wide range of GPIO pins. It supports MicroPython, C, and C++, making it accessible to beginners and powerful enough for advanced developers. Because it is small, affordable, and energy-efficient, the Pico has become popular for robotics, sensors, automation, and educational projects.

One of the reasons people ask “Does Raspberry Pi Pico Have Wifi?” is that many modern microcontroller boards include wireless connectivity by default. The original Pico focused on core microcontroller features rather than connectivity, keeping the price low and the design simple.

Does Raspberry Pi Pico Have Wifi? The Detailed Answer

To answer “Does Raspberry Pi Pico Have Wifi?” in detail, it helps to separate the original Pico from the Pico W. The original Raspberry Pi Pico, released in 2021, has no WiFi and no Bluetooth. It relies entirely on wired connections such as USB, UART, SPI, and I2C for communication.

The Raspberry Pi Pico W, released in 2022, adds a wireless chip to the same RP2040 foundation. This chip provides 2.4 GHz WiFi and Bluetooth 5.2 support. Aside from the wireless module and a few minor layout changes, the two boards are nearly identical in processing power and pin layout.

So when someone asks “Does Raspberry Pi Pico Have Wifi?”, the most accurate response is: the original does not, but the Pico W does. Always check the exact model name before purchasing or starting a project.

Raspberry Pi Pico vs Raspberry Pi Pico W

The table below compares the two boards so you can choose the right one for your needs.

Feature Raspberry Pi Pico Raspberry Pi Pico W
Microcontroller RP2040 RP2040
CPU Dual-core Arm Cortex-M0+ up to 133 MHz Dual-core Arm Cortex-M0+ up to 133 MHz
SRAM 264 KB 264 KB
Flash Storage 2 MB 2 MB
WiFi No Yes, 2.4 GHz
Bluetooth No Yes, Bluetooth 5.2
GPIO Pins 26 26
USB Micro-USB Micro-USB
Typical Use Case Wired embedded projects IoT and wireless projects

As you can see, the main difference is wireless connectivity. If your project involves sending data over a network, the Pico W is the clear choice.

Hardware Overview of the Raspberry Pi Pico

Understanding the hardware helps explain why the original board lacks WiFi. The RP2040 chip is focused on general-purpose input and output, timing, and processing. It does not include a radio. Adding WiFi would require additional silicon, antenna hardware, and certification, which would increase cost and complexity.

The Pico W solves this by pairing the RP2040 with a wireless module, specifically an Infineon CYW43439. This module handles the radio and network stack, leaving the RP2040 free to run your application code. The two communicate internally, so from a programming perspective, WiFi feels like a built-in feature.

Both boards share the same GPIO layout, which means most accessories, breadboard setups, and code examples work on either board. This backward compatibility is one reason the Pico family remains popular.

How to Add WiFi to a Standard Raspberry Pi Pico

If you already own the original Pico and need network access, you do not necessarily have to buy a new board. You can add WiFi using an external module. Here is a step-by-step approach.

  1. Choose a wireless module. Common options include the ESP8266, ESP32, or specialized WiFi add-on boards designed for the Pico. The ESP8266 is inexpensive and widely supported.
  2. Connect the module. Use UART, SPI, or I2C to link the module to the Pico’s GPIO pins. Follow the module’s wiring diagram carefully.
  3. Power the setup. Ensure your power supply can handle both the Pico and the wireless module. A stable 3.3V or 5V supply is usually required.
  4. Install firmware. Flash appropriate firmware onto the wireless module. For ESP8266, AT firmware is a common starting point.
  5. Write communication code. Use MicroPython or C to send commands from the Pico to the module. Libraries exist to simplify this process.
  6. Test the connection. Connect to your WiFi network and verify that data can be sent and received.
  7. Secure the project. Add error handling, reconnection logic, and security measures such as TLS where possible.

This approach works well, but it adds complexity, wiring, and power requirements. For many users, buying a Pico W is simpler and more cost-effective.

Using the Wireless Features of the Pico W

Once you have a Pico W, using WiFi is straightforward. In MicroPython, the network module provides the tools you need. A typical workflow looks like this:

import network
import time

wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect("your-ssid", "your-password")

while not wlan.isconnected():
    time.sleep(1)

print("Connected:", wlan.ifconfig())

This code activates the wireless interface, connects to your network, and prints the assigned IP address. From there, you can make HTTP requests, run a small web server, or communicate with MQTT brokers.

The Pico W also supports access point mode, allowing it to create its own WiFi network. This is useful for configuration portals or device-to-device communication without an existing router.

Performance, Range, and Limitations

When evaluating “Does Raspberry Pi Pico Have Wifi?”, it is also worth considering how well the wireless performs. The Pico W uses 2.4 GHz WiFi, which offers good range and compatibility with most routers. However, it does not support 5 GHz networks.

Range is generally solid indoors, though walls and interference can reduce signal strength. The onboard antenna is compact, so placing the board in a metal enclosure may weaken the signal. Adding an external antenna is possible with modifications, but that is an advanced topic.

Power consumption is another consideration. Wireless communication draws more current than idle operation. If you are building a battery-powered device, plan your power budget carefully and use sleep modes when possible.

Tips and Best Practices

Here are some practical tips to get the most out of your Pico or Pico W:

  • Verify the model. Always check the board label before assuming WiFi is available.
  • Use the latest firmware. Keep MicroPython or your C SDK updated for bug fixes and performance improvements.
  • Manage power. Use sleep modes and disable WiFi when not needed to extend battery life.
  • Secure your network. Use strong passwords and consider encrypted communication for sensitive data.
  • Test early. Verify wireless connectivity before building the rest of your project.
  • Document your setup. Keep notes on wiring, credentials, and code versions for easier troubleshooting.
  • Use a proper power supply. Unstable power can cause random resets, especially with wireless modules.

Common Projects That Use WiFi

The Pico W opens the door to many connected projects. Popular examples include smart home sensors, weather stations, remote data loggers, and small web servers. Because the board is inexpensive, it is ideal for experimenting with IoT concepts.

For projects that do not need connectivity, the original Pico remains an excellent choice. It handles tasks like motor control, LED displays, and sensor reading with ease. The key is matching the board to the requirement rather than assuming every Pico has WiFi.
