The Raspberry Pi Pico W is a wireless-enabled microcontroller development board based on the RP2040 platform. It integrates 2.4 GHz IEEE 802.11 b/g/n Wi-Fi connectivity, extending the Pico family for networked embedded applications. The board is powered by the RP2040 dual-core ARM Cortex-M0+ processor running at up to 133 MHz, with 256 KB SRAM and 2 MB onboard QSPI Flash memory. Wireless connectivity is provided by the Infineon CYW43439 controller, with WLAN support available at launch. Suitable for IoT prototypes, remote sensing, wireless control systems, and embedded development projects.
