Raspberry Pi Pico 2 W 板卡记录：RP2350，经板上 CYW43439 无线芯片提供 Wi-Fi 与蓝牙，4 MB flash，与 Pico W 相同的 40 针 J1/J2 布局，LED 在无线芯片而非 GP25，每个发布字段都有固定官方来源。

J1 (left header, physical pins 1-20) (20 针位) Pin table reused from the verified Raspberry Pi Pico record: the official docs state the wireless boards share one pinout and board layout, and the SDK board header pico2_w.h sets identical UART/I2C/SPI defaults. Physical pins, silkscreen names and power/ground positions are therefore the same 40 positions as the Pico. Board-level differences from the Pico/Pico 2 are carried as claims on this record (LED wiring, GP23/24/29 radio use, SWD position), not as pin-table edits. · 来源: Raspberry Pi documentation: Pico-series boards (pinout figures, board differences, SWD connector) · documentation/asciidoc/microcontrollers/pico-series/about_pico.adoc#layout_wireless

Raspberry Pi Pico 2 W 是无线的 RP2350 板：板上集成 Infineon CYW43439 无线芯片（Wi-Fi 802.11n 2.4 GHz、蓝牙 5.2），经 SPI 连接 MCU， 4 MB flash、micro-USB B，以及与 Pico W 相同的 40 针封装与针位——官方文档声明无线板共用同一布局与针位。本页渲染 MCUID 的板卡数据记录与每个字段的固定官方来源。
开始开发 本站回答的常见问题 又名: pico 2 w, pico2w, raspberry pi pico 2 w, rpi pico 2 w
与 Pico W 相同——除了芯片与 flash 布局、无线芯片、内部 GPIO 接线与 SWD 位置 与 Pico W 完全一致 （官方文档把无线四型放在一起描述）。变化的是：
RP2350 取代 RP2040 ——双核 Arm Cortex-M33 或双核 Hazard3 RISC-V（可选），150 MHz、520 kB SRAM；切换意味着什么见 RP2350 芯片页 。 4 MB flash 取代 2 MB （SDK 板级头文件 PICO_FLASH_SIZE_BYTES）。 Pico W 页 的无线电路说明在这里逐条适用：LED 在无线芯片（WL_GPIO0）、GP23/24/25/29 被无线占用（GP25 = 无线 SPI 片选，GP29 = SPI 时钟与 VSYS 监控共享）、SWD 焊盘在 MCU 正下方中央（左到右 SWCLK、GND、SWDIO）。
烧录：BOOTSEL、卷名 RP2350——选对固件 插 USB 时按住 BOOTSEL ，板卡枚举为名为 RP2350 的大容量存储卷——与非无线的 Pico 2 同名，所以 卷名本身不能区分 W 与非 W 。请核对板卡本身（见识别指南）。固件目标有三重区分： pico2_w ≠ pico2 ≠ pico_w。
无线：能力与许可 与 Pico W 相同：CYW43439、Wi-Fi 802.11n 2.4 GHz（WPA3、soft-AP 最多四客户端）、蓝牙 5.2（BLE Central/Peripheral + Classic）；按树莓派授予的许可， libcyw43/ BTstack 对无线 Pico 板免费商用。
