The Raspberry Pi Pico W takes the original RP2040-based Pico design and adds wireless connectivity, described by Raspberry Pi as doing for microcontrollers what the original Raspberry Pi computer did for single-board computing. At its core is the same RP2040 chip as the wired Pico: a dual-core Arm Cortex-M0+ processor running at 133MHz, now paired with 2MB of onboard flash memory, twice the flash of the earliest Pico boards, giving more room for networking libraries and application code.
Wireless is a single-band 2.4GHz 802.11n interface, added onboard rather than through an external module, which keeps the board's compact 40-pin DIP-style footprint unchanged from the original design.
Onboard memory includes 264KB of SRAM alongside the 2MB of QSPI flash. The board exposes 26 multi-function GPIO pins at 3.3V logic, three of which double as analogue inputs, plus a 3-pin ARM SWD port for hardware debugging. A Micro USB B port handles both power and programming, so getting code onto the board needs only a standard USB cable.
Input power range is 1.8 to 5.5V DC, and the board operates between -20C and 70C, a slightly narrower range than the newer Pico 2 W, since it uses the earlier RP2040 chip rather than the RP2350.
Anyone building a simple WiFi-connected sensor, a home automation node or a project migrating from the wired Pico to add networking will find the Pico W a straightforward, low-cost step, without leaving the RP2040 ecosystem or its existing tooling behind.
