Raspberry Pi Pico W Wireless RP2040 MCU Board is a compact wireless RP2040 development board built around the official Raspberry Pi RP2040 microcontroller and the Infineon CYW43439 wireless chip. It is a strong fit for wireless IoT nodes, MicroPython learning, embedded control, sensor networking, home automation, and low-power connected devices.
Raspberry Pi Pico W adds 2.4GHz Wi-Fi and Bluetooth 5.2 capability to the Pico platform while keeping the small form factor, dual-core Arm Cortex-M0+ architecture, and flexible GPIO and PIO features. This product page covers multiple official Waveshare package options, including Pico W Original, Pico WH Original, Pico W with pre-soldered header, Pico W Relay Kit, Pico W Basic Kit, and Pico W Evaluation Kit.
Important: According to the manufacturer Raspberry Pi, this product cannot be shipped and technical support cannot be provided to Cuba, Iran, North Korea, Syria, Crimea, Donetsk, Luhansk, Russia, and Belarus.

Why Pico W matters
The biggest upgrade over the standard Pico is the addition of Wi-Fi and Bluetooth, which makes it much easier to build compact wireless controllers, remote sensors, and connected embedded devices without adding a separate radio module.
Choosing the right package
If you want the bare board, choose Pico W Original or Pico WH Original. If you want an entry-level learning package, the Basic Kit is more suitable. If you need relay control, choose the Relay Kit. If you want a more feature-rich display and sensor setup, the Evaluation Kit is the better fit.
Header note
The Pico WH and the pre-soldered header version are easier to plug into boards and expanders, but they do not keep the castellated-hole form factor used on the original Pico W board.

FAQ
What is the difference between Pico W and Pico WH?
Pico WH is the official version with a pre-soldered header. The original Pico W keeps the castellated-hole form factor.
Which version should I choose?
Choose Pico W Original for the bare wireless board, Pico WH Original for easier plug-in use, Relay Kit for wireless switching control, Basic Kit for beginner sensor experiments, and Evaluation Kit for display and IMU testing.
Does it support wireless connectivity?
Yes. Raspberry Pi Pico W supports 2.4GHz Wi-Fi 4 and Bluetooth 5.2.
What is it best used for?
It is especially suitable for wireless IoT, MicroPython learning, home automation, relay control, sensor networking, and custom RP2040 development.
