WSAL23104 – Raspberry Pi Pico W/en

Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.

Summary

The Raspberry Pi Pico W is the wireless successor to the standard Pico. It uses the RP2040 dual-core processor designed by Raspberry Pi and adds an integrated 2.4 GHz Wi-Fi chip (Infineon CYW43439). The board provides 26 multi-function GPIOs, a USB 1.1 port with device and host support, and drag-and-drop programming via mass storage over USB.

Notes and version constraints

No explicit commands or CLI instructions are present in the source; do not invent command syntax.
Exact pinout details are only referenced, not reproduced – verify against the original source documents.
Version-sensitive steps (firmware updates, MicroPython/SDK setup) require human confirmation since they depend on the specific software version in use.
The source contains template placeholders ({{{name2}}} etc.), indicating incomplete templates – full specifications should be cross-checked against official datasheets.
No pricing, stock, certification, or warranty information appears in the source; such claims must not be invented.
