Description

The Raspberry Pi Pico W is the wireless version of the popular Raspberry Pi Pico, combining the powerful RP2040 dual-core microcontroller with built-in 2.4GHz Wi-Fi to create an excellent platform for connected electronics and IoT projects. Whether you’re building a Wi-Fi sensor node, smart home controller, web-enabled robot, or remote monitoring device, the Pico W delivers strong performance, low cost, and a clean development experience.

At its heart is the RP2040, featuring two Arm Cortex-M0+ cores running up to 133MHz, plus plenty of GPIO and flexible peripheral support. You can program it using MicroPython, C/C++, or the Arduino IDE, making it suitable for beginners and advanced developers alike.

Built-In Wi-Fi for IoT Projects

Pico W includes integrated 2.4GHz 802.11n Wi-Fi, allowing you to:

Send sensor readings to a server or dashboard
Control relays/LEDs/motors over a network
Build web servers, MQTT clients, and Wi-Fi automation projects
Create wireless robotics controllers and remote telemetry

Key Features & Benefits

Wi-Fi Enabled Microcontroller Board: Built-in wireless reduces extra modules and wiring
Dual-Core Performance: Two cores help handle real-time control and networking tasks
MicroPython Friendly: Great for quick IoT prototypes and learning
Arduino Compatible: Use familiar libraries and rapid development workflows
26 GPIO Pins: Plenty of I/O for sensors, displays, relays, and drivers
ADC + PWM + Serial Buses: Supports I2C, SPI, UART, PWM, and analog inputs
UF2 Drag-and-Drop Programming: Easy firmware flashing over USB
