Several blue robotic vehicles with wheels lined up

The short answer is no: the standard Raspberry Pi Pico does not have built-in WiFi, but the Pico W version does. When you ask, “Does Raspberry Pi Pico have WiFi?“, you are likely holding the wrong board for your IoT dream.

We once spent three frantic hours soldering wires to a standard Pico, convinced we missed a hidden switch, only to realize the chip simply lacks the radio. It turns out, the original Pico was designed for pure, local control, leaving wireless connectivity to its “W” sibling.

This distinction is critical because buying the wrong board can derail your entire robotics project before you even write a line of code. The standard Pico is a powerhouse for local logic, while the Pico W is your gateway to the internet.

Key Takeaways

  • Standard Pico = No WiFi: The original board has zero wireless capabilities; you must add external modules.
  • Pico W = Built-in WiFi: The “W” variant includes native 802.1 b/g/n WiFi and Bluetooth 5.2.
  • External Options Exist: You can add WiFi to a standard Pico using modules like the ESP-01, but it requires extra wiring and code.
  • Power vs. Convenience: Choose the standard Pico for battery efficiency and the Pico W for remote connectivity.

⚡️ Quick Tips and Facts

Before we dive into the nitty-gritty of circuit boards and code, let’s cut through the noise with some hard truths about the Raspberry Pi Pico. If you’re here because you bought a standard Pico and are frantically searching for a WiFi antenna, stop right there.

  • The Standard Pico has NO WiFi. It does not have a single radio chip on board. Zero. Zilch. Nada. 🚫
  • The Pico W is the WiFi version. The “W” stands for Wireless. If you need connectivity out of the box, you need the Pico W.
  • The Core is the Same. Both boards run on the RP2040 microcontroller chip designed by Raspberry Pi. The difference is purely the add-on wireless module.
  • You Can Add WiFi. Don’t panic! You can connect external modules (like the ESP-01) to the standard Pico to get it online.
  • It’s Not a Computer. Despite the name, the Pico is a microcontroller, not a full Linux computer like the Raspberry Pi 4. It doesn’t run an OS; it runs your code directly.

Wait, why did Raspberry Pi make two versions? We’ll get to that juicy history lesson in a moment, but the short answer is: cost vs. convenience.

📜 The Untold History: How the Raspberry Pi Pico Evolved Without Built-in WiFi

green and black circuit board

Let’s take a trip down memory lane. When the original Raspberry Pi Pico launched in early 2021, it was a shock to the system. For years, the Raspberry Pi Foundation had been churning out single-board computers (SBCs) that were essentially tiny Linux PCs. Then, they dropped a microcontroller board.

The goal was simple: create a cheap, accessible board for robotics, IoT, and embedded projects that didn’t require the overhead of an operating system. The RP2040 chip was the star of the show. It was powerful, dual-core, and incredibly affordable.

But here’s the twist: Why no WiFi?

At the time, adding a WiFi chip (like the CYW43439 found in the Pico W) would have increased the cost and complexity of the board. The Foundation wanted the base Pico to be the absolute cheapest entry point possible. They prioritized raw GPIO pins and processing power over wireless connectivity.

Fast forward to June 202, and the Raspberry Pi Pico W arrived. It included the same RP2040 but added the wireless module. This created a bit of confusion in the community. Was the original Pico “obsolete”? Absolutely not. For battery-powered devices where you don’t need constant internet, the standard Pico is still a beast. But for IoT? The Pico W became the new darling.

Curious about the specific chip that makes the magic happen? We’ll break down the silicon architecture in the next section.

🔍 Does the Raspberry Pi Pico Have WiFi? The Definitive Hardware Breakdown

Let’s address the elephant in the room with a definitive Yes or No.

Does the standard Raspberry Pi Pico have WiFi?
❌ No.

Does the Raspberry Pi Pico W have WiFi?
✅ Yes.

It’s that simple, but let’s look under the hood. The standard Pico is built around the RP2040 SoC (System on Chip). This chip handles the logic, the math, and the GPIO control. It does not contain a radio transceiver. If you look at the board, you won’t see any antenna traces or a secondary chip for wireless communication.

The Pico W, however, adds the CYW43439 wireless chip. This chip handles both WiFi (802.1 b/g/n) and Bluetooth 5.2.

Hardware Comparison: Pico vs. Pico W

Feature Raspberry Pi Pico (Standard) Raspberry Pi Pico W
Microcontroller RP2040 RP2040
WiFi Capability ❌ None (Requires external module) ✅ Built-in (802.1 b/g/n)
Bluetooth ❌ None ✅ Bluetooth 5.2
Antenna None PCB Trace Antenna
Price Point Lower Slightly Higher
Best For Battery life, cost-sensitive, local control IoT, remote control, web servers

If you are looking at a board and see a small chip near the USB port that looks like a tiny black square with a metal shield, that’s likely the CYW43439 on a Pico W. If the board is just the RP2040 and a few passive components, it’s the standard Pico.

But what if you already have the standard Pico? Can you still get it online? The answer is a resounding yes, and we’ll show you exactly how to do it without throwing your board in the trash.

So, you have the standard Pico, and you need WiFi. Don’t panic! You have options. Here are five proven methods to get your standard Pico online.

  1. ESP-01 Module (Serial Bridge): The classic, budget-friendly choice. You connect an ESP-01 to the Pico via UART (Serial). The Pico sends commands, and the ESP-01 handles the WiFi.
  2. ESP32 Co-Processor: Use an ESP32 as a “slave” to the Pico. The ESP32 handles the heavy lifting of WiFi, while the Pico handles the robot logic.
  3. USB-to-WiFi Dongle: Yes, you can plug a standard USB WiFi adapter into the Pico’s USB port, though driver support in MicroPython can be tricky.
  4. SPI WiFi Modules: Modules like the W50 (Ethernet) or specific SPI-based WiFi chips can be connected via the SPI bus for faster data transfer.
  5. Grove or Qwic Adapters: Use a pre-made WiFi shield that plugs into the Pico’s GPIO headers, simplifying the wiring process.

Which method is right for you?

  • For beginners: The ESP-01 is the most documented and easiest to find.
  • For performance: The ESP32 offers more processing power and better range.
  • For simplicity: A Grove WiFi module reduces soldering headaches.

⚙️ Step-by-Step: Wiring an ESP-01 to Your Pico for Wireless Magic


Video: Raspberry Pi Pico W LESSON 28: Connecting the Raspberry Pi Pico W to WiFi.








Let’s get our hands dirty. We are going to wire an ESP-01 to the Raspberry Pi Pico. This is the most common “hack” to add WiFi.

The Wiring Logic

The Pico will act as the Master, and the ESP-01 will act as the Slave. We will use the UART (Serial) protocol.

  1. Power: Connect the 3V3 pin on the Pico to the VCC on the ESP-01.
  2. Ground: Connect GND on the Pico to GND on the ESP-01.
  3. Data (TX/RX):
  • Connect Pico GPIO 0 (UART0 TX) to ESP-01 RX.
  • Connect Pico GPIO 1 (UART0 RX) to ESP-01 TX.
    Note: Ensure you cross the wires! TX goes to RX, and RX goes to TX.
  1. Enable: Connect the CH_PD (or EN) pin on the ESP-01 to 3V3 on the Pico to keep it powered on.

The Code Snippet (MicroPython)

Here is a simplified example of how you might send an AT command to the ESP-01 from the Pico:

import machine
import time

# Setup UART
uart = machine.UART(0, baudrate=1520, tx=machine.Pin(0), rx=machine.Pin(1))

def send_at_command(command):
 uart.write(command + b'\r\n')
 time.sleep(0.5)
 if uart.any():
 print(uart.read().decode())

# Reset the ESP-01
send_at_command(b'AT+RST')
time.sleep(2)

# Connect to WiFi
send_at_command(b'AT+CWJAP="YourSSID","YourPassword"')

Does this work perfectly every time? Not always. The ESP-01 can be temperamental. If you get “ERROR” responses, check your wiring and ensure the baud rate matches.

💻 Coding the Connection: MicroPython and C++ Libraries for Pico WiFi Add-ons


Video: Raspberry Pi Pico Wifi Module – how to add Wifi to your Pico Projects.








Once the hardware is wired, you need to speak the language. The MicroPython environment on the Pico is fantastic for this.

Using urequests with ESP-01

You can use the urequests library in MicroPython to make HTTP requests, but you have to handle the serial communication to the ESP-01 first. This is where it gets tricky. You have to write a wrapper class that translates HTTP requests into AT commands for the ESP-01.

The Pico W Advantage

If you were using the Pico W, you would simply use the network and socket libraries built into the firmware. No AT commands, no serial wiring. It’s native.

# Pico W Native Code (for comparison)
import network
import time

wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('YourSSID', 'YourPassword')

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

print('Connected!')

For the standard Pico with ESP-01, you are essentially writing a driver. This is a great learning experience for understanding serial communication and state machines, but it adds complexity to your code.

Is the extra coding worth it? If you already have the parts, yes. If you are starting from scratch, the Pico W saves you hours of debugging.

🚀 Performance Showdown: Native WiFi (Pico W) vs. Serial-to-WiFi Modules


Video: Raspberry Pi Pico W – the new Raspberry Pi Pico with Wifi.








Let’s talk numbers. How does the native WiFi of the Pico W compare to the ESP-01 bridge on the standard Pico?

Metric Pico W (Native) Pico + ESP-01 (Serial)
Latency Low (Direct access) High (Serial overhead)
Throughput ~10-15 Mbps ~1-2 Mbps (limited by UART)
Stability High Variable (depends on AT command timing)
Code Complexity Low High (Custom driver needed)
Power Efficiency Optimized Poor (ESP-01 always on)

The Verdict:
The Pico W is superior in every performance metric. The serial bridge method introduces a bottleneck. The UART speed limits your data transfer, and the overhead of sending AT commands adds latency.

However, for a simple sensor that sends a temperature reading once a minute? The ESP-01 bridge is perfectly adequate. It’s a trade-off between performance and cost.

But what about security? Can you trust these external modules to keep your robot safe? Let’s dive into that.

Security is often an afterthought in the hobbyist world, but it shouldn’t be. Whether you are using the Pico W or an ESP-01, you are exposing your device to the network.

Common Vulnerabilities

  1. Default Credentials: Never leave default passwords on your WiFi network.
  2. Unencrypted Traffic: If you are sending data over HTTP, anyone on the same network can sniff it. Use HTTPS (TLS) if possible.
  3. Firmware Updates: Ensure your ESP-01 or Pico W firmware is up to date. Old firmware has known exploits.

Best Practices for Robotic Coding™

  • Use WPA2/WPA3: Always secure your WiFi network.
  • Isolate IoT Devices: Put your robots on a separate Guest Network so they can’t access your main computer or files.
  • Validate Inputs: If your robot accepts commands over WiFi, validate them strictly to prevent injection attacks.

How do you know if your connection is secure? We’ll cover how to verify your connection in the FAQ section.

💡 Quick Tips and Facts

Wait, we mentioned this earlier, but let’s reiterate with a twist!

  • The “W” is not a software update. You cannot “unlock” WiFi on a standard Pico by flashing new code. It’s a hardware limitation.
  • Bluetooth is also missing. The standard Pico has no Bluetooth either. If you need to connect to a phone via Bluetooth, you need the Pico W or an external module.
  • Antenna placement matters. If you are using an external module, keep the antenna away from metal parts of your robot to avoid signal interference.
  • Power spikes. WiFi transmission causes power spikes. If your robot resets when it tries to connect, you might need a capacitor or a better power supply.

Still have questions? We’ve got a massive FAQ section coming up to answer everything you didn’t know you needed to ask.

🏁 Conclusion

green and black circuit board

So, does the Raspberry Pi Pico have WiFi? The answer is a nuanced it depends.

  • The Standard Pico: ❌ No WiFi. It is a pure, unadulterated microcontroller. It’s perfect for local control, battery efficiency, and cost-sensitive projects. If you need WiFi, you must add it externally, which adds complexity and cost.
  • The Pico W: ✅ Yes, WiFi. It comes with built-in WiFi and Bluetooth, making it the go-to choice for IoT, remote control, and cloud-connected robots.

Our Recommendation:
If you are starting a new project and need connectivity, buy the Pico W. The price difference is negligible, and the convenience of native support is worth every penny. You save hours of debugging serial bridges and dealing with AT commands.

However, if you are building a swarm of robots where every cent counts, or if your robot operates in a faraday cage (no signal needed), the standard Pico is still a fantastic choice. Just remember to plan your external WiFi strategy early.

The narrative is resolved: You don’t need to throw away your standard Pico, but for most modern robotics and IoT applications, the Pico W is the superior tool.
