Raspberry Pi Pico W Overview

The Raspberry Pi Pico W is a robust, low-cost microcontroller designed by the Raspberry Pi Foundation for innovative IoT applications. Featuring the RP2040 chip, this board introduces WiFi and Bluetooth Low Energy (BLE) capabilities, transforming single-board microcontrollers with wireless connectivity and streamlined functionality. The Pico W retains the form factor of the classic Pico, offering full GPIO pin compatibility alongside the new single-band 2.4GHz wireless interface, which integrates Infineon’s CYW43439 chip for reliable WiFi performance. With 2MB QSPI flash memory and 264KB SRAM, this dual-core ARM Cortex-M0+ microcontroller is ready for versatile projects in CircuitPython, MicroPython, and C/C++, making it ideal for beginner and advanced embedded electronics enthusiasts alike.
