WiFi-enabled Raspberry Pi Pico W

ESP8266 - killer... for sure!

I woke up to rather lovely news about the Raspberry Pi Pico board. The last Pico microcontroller was released by Raspberry Pi a couple of months ago and just got treated to a wireless upgrade! That’s right, Raspberry Pi Pico W brings WiFi to a familiar RP2040 platform.

The new board retains the same form factor and it’s trading the Raspberry Pi logo space for a WiFi and Bluetooth-enabled CYW43439 wireless chip. It brings the 802.11 b/g/n wireless (2.4GHz) LAN and Bluetooth 5.2. It’s still RP2040 based – the same chip used in the original Raspberry Pi Pico, featuring two ARM Cortex-M0+ cores clocked at 133MHz; 256KB RAM and offering 30 GPIO pins.

This will make a lot of makers happy, especially those who argued that ESP32/8266 platforms were offering much more features at a similar price point. Raspberry Pi Pico W costs $6 and right now is limited to one board per customer.

As the Raspberry Pi has an excellent track record when it comes to supporting for its hardware, a WiFi-enabled microcontroller like this finally gives a great reason to leave ESP8266 projects behind and take advantage of all Pico features including excellent I/O choice and PIO.

Pi Pico W specification

  • RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom
  • Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz
  • 264kB of SRAM, and 2MB of onboard Flash memory
  • Infineon CYW43439 wireless chip
    • IEEE 802.11n wireless LAN
    • Bluetooth 5.2 (not software supported at launch)
    • WPA3
    • SoftAP (up to 4 clients)
    • Onboard antenna licenced from ABRACON (connected via SPI to the RP2040)
  • The castellated module allows soldering directly to carrier boards
  • USB 1.1 Host and Device support
  • Low-power sleep and dormant modes
  • Drag & drop programming using mass storage over USB
  • 26 multi-function GPIO pins

  • Real-time clock (RTC)
  • Temperature sensor
  • Accelerated floating-point libraries on-chip
  • 8×Programmable IO (PIO) state machines for custom peripheral support
  • Dimensions (WxLxH)
    • Pico W: 21mm x 51.3mm x 3.9mm

Not everything at once

While Raspberry Pi Pico W brings WiFi and Bluetooth 5.2, not everything will be supported at launch. Micropython takes precedence over C++ and anyone who wants to tinker with the latest WiFi on a Raspberry Pi Pico W will have to wait until supported libraries for C++ are released.

At the time of writing, there are no estimated timelines for further software and library support but I have confidence we will see these coming to the new Pico board soon.

RP2040 & its future

My Raspberry Pi Pico W is already on its way and should arrive tomorrow or the day after. I will definitely have a short overview or a live stream, soo keep your eyes peeled on my social media.

I’m pleased to see Raspberry Pi supporting the platform well and continuing its development. As Raspberry Pi Pico W is a straight-up drop-in replacement, if you want to bring WiFI capabilities to your project, the upgrade is as simple as replacing the board and adding software functionality.

You can read more about Raspberry Pi Pico W in the official Raspberry Pi blog post. Let me know if you have any questions in this Reddit thread.

How to use Raspberry PI as WOL (wake on lan) server

While you could wake up your PC from a mobile directly, having a dedicated server capable of doing so is the best solution. The reason is simple. You can hook up as many devices as you wish with a single endpoint. This is why Raspberry Pi is perfect for this.

Slow Internet Warning

From time to time my Internet grinds to a stop. Since Raspberry Pi 4 comes with a 1Gbps Ethernet, I decided to take advantage of it and create a reporting system in NodeRED that will monitor and report when the ISP is not keeping the contractual agreements. Works with Alexa, Google Home, Android and Windows 10.
