Raspberry Pi Pico 2 W - RP2350 WiFi/Bluetooth Microcontroller Board

The wireless variant of the Pico 2: the same RP2350 dual-core chip as the standard Pico 2, plus an Infineon CYW43439 radio for 2.4GHz WiFi and Bluetooth 5.2 (LE), matching how the original Pico W added wireless to the RP2040. Same 21mm x 51mm form factor and pinout as Pico 2 and the original Pico W.

Specifications

• Chip: RP2350 (dual-core Arm Cortex-M33 @ 150MHz, or dual-core RISC-V Hazard3)
• SRAM: 520KB, Flash: 4MB onboard QSPI
• Wireless: Infineon CYW43439, 802.11n WiFi (2.4GHz) + Bluetooth 5.2 LE
• GPIO: 26 multi-function pins (radio uses some internally, same tradeoff as Pico W)
• Operating voltage: 1.8-5.5V input via USB or VSYS
• Programming: MicroPython, CircuitPython, or C/C++ SDK

When to choose this over the plain Pico 2

Pick the W variant for anything that needs to talk to a network -- MQTT sensor nodes, web-controlled devices, OTA updates. Pick the plain Pico 2 for cost-sensitive or purely local/wired projects (motor control, USB HID, audio) where you don't need the radio.
