NUCLEO-F401RE 是意法半导体为 STM32F401RET6（LQFP64）推出的评估板：兼容 Arduino Uno V3 的外形与四组 Arduino 排针（CN6 电源、CN8 模拟、CN5 与 CN9 数字），双排 ST morpho 连接器 CN7/CN10 从板两侧引出全部微控制器信号，另有 6 针 SWD 调试连接器 CN4 与板载 ST-LINK/V2-1 调试器——一根 micro-USB 线即可供电并烧录。本页渲染 MCUID 数据档案：七个连接器共 114 个触点、板卡修订，以及每个已发布字段与其固定来源。

开始开发

芯片事实 — STM32F401RE 芯片页区分芯片本身提供的能力与这块板的接线。
官方手册 — 下方每张触点表都链接到 UM1724 Rev 17，这是覆盖本板的唯一手册（st.com 免费下载）。

没有模组层

与 Raspberry Pi Pico 一样、与 Espressif 评估板不同，NUCLEO-F401RE 没有模组层：STM32F401RET6 直接焊在板上。兼容模组列表留空——没有需要虚构的模组记录。

连接器体系速览

CN6 / CN8 / CN5 / CN9 是四组 Arduino Uno V3 单排母排针（电源、模拟、数字 1-10、数字 1-8）。能插上 Uno R3 的扩展板就能插上这里。
CN7（公）与 CN10（母） 是 ST morpho 连接器：各为 2×19 针，奇数针构成一排、偶数针构成另一排，两排均可从板的顶面与底面接入。Arduino 侧的每个信号在这里都能找到，此外还有 Arduino 没有的信号（PC9、PC5、PA12、PB12-PB15 等）。
CN4 是接到板载 ST-LINK/V2-1 的 6 针 SWD 调试连接器。手册 7.4.5 节说明如何用它给外部应用编程。

两个信号带有明确的焊桥选择：A4 为 PC1 或 PB9，A5 为 PC0 或 PB8（见表 10 焊桥）。CN7 的 35/37 针展示同样的选择。

我手上是哪个板卡修订？

PCB 修订丝印在板上为 MB1136-F401RE-C0x。共四个修订——C01（初始）、C02（HSE 焊桥 SB16/SB50 变更）、C03（LSE 晶振 X2 料号变更）、C04（晶体管 T2 料号变更）——没有任何修订改变连接器引脚分配：手册的引脚表对四个修订全部适用。在引脚图上方选择你的修订即可查看对应的变更说明。

板上可能还有 Z 或 1 标记——那是MCU 的硅修订，不是 PCB 修订；板上装配的 MCU 为 STM32F401RET6，勘误表 ES0299。
