Arduino Nano ESP32

类型：板卡 · 厂商: arduino · 芯片: ESP32-S3

Nano form factor (18 x 45 mm, 2 x 15 pin headers at 2.54 mm pitch) development board with a soldered u-blox NORA-W106-10B radio module embedding the ESP32-S3. Single USB-C port for power, flashing and serial; 16 MB on-board flash (U3), 8 MB PSRAM inside the module; 3.3 V logic; VIN 6-21 V; no 5 V pin (VBUS only). Pins carry Arduino Nano silkscreen names (Dn/An) whose native GPIO numbers differ - see the pin-numbering guide.

Arduino Nano ESP32 是一块 18 × 45 mm 的 Nano 封装板，射频部分是内含 ESP32-S3 的 u-blox NORA-W106-10B 模组——与 ESP32-S3-DevKitC-1 同一芯片家族，但按 Arduino Nano 引脚布局封装，而不是乐鑫评估板布局。单一 USB-C 口负责供电、烧录与串口；整板 3.3 V 运行。本页渲染 MCUID 数据记录：完整 2 × 15 排针映射、板与模组之间的存储拆分，以及每个发布字段对应的固定官方来源。

两个事实让这块板在本站显得特别：

你看到的引脚号不是芯片用的 GPIO 号。 丝印沿用经典 Nano 编号（D0–D13、A0–A7）；每个引脚背后的 ESP32-S3 原生 GPIO 并不相同（D2 是 GPIO5、D8 是 GPIO17……）。引脚编号指南带你走完两套编号和 IDE 里的切换开关。
存储拆分与乐鑫模式不同。 16 MB flash 是板上芯片（U3），不在模组内；8 MB PSRAM 在 NORA-W106 模组内部。WROOM/WROVER 板上两者都在模组里。

开始开发

上手——Arduino 官方入门指南覆盖 IDE 安装与板包（Arduino ESP32 core 2.x）。
引脚编号——接线前先读这块板的 Dn 与 GPIO。
芯片能力与边界——ESP32-S3 芯片页区分芯片提供什么与这块板接出了什么。

值得先知道的供电事实

VIN 接受 6–21 V；板载 MP2322GQH 稳压器降到 3.3 V。
没有 5 V 引脚。 只有 VBUS 提供 5 V，直接来自 USB-C 电源——而且经 VIN 供电时 VBUS 不会被驱动。因此 5 V 外设需要 USB 供电或独立电源。
I/O 在 3.3 V 电平；3.3 V / 5 V 信号指南解释为什么这一点软件谈不了。

无需外部工具的恢复

如果某个程序把板卡锁死，官方文档的恢复方法是上电后快速连按两下复位按钮——板进入 bootloader，可再次经 USB 烧录。

同芯片，不同板

从 ESP32-S3-DevKitC-1 过来？同一芯片家族，接线却很不一样：DevKitC 在排针上暴露模组原生 GPIO 编号并提供模组家族选择；这块板把原生编号藏在 Nano 丝印后面并焊死单一模组。引脚编号概念指南把这些层次拆开。

JP1 (analog-side 1x15 header) 触点表

Positions, names and descriptions transcribed from the datasheet's Analog (JP1) table; native GPIO numbers from the official pin-setup pin map (same repository and commit). The datasheet lists type 'NC' for position 1 (D13/SCK) - treated here as digital I/O per its own description; type letters on this board are MCUID's editorial summary of the datasheet types (Analog/Digital -> I/O, Mode -> I, Power -> P, Ground -> G). BOOT0/BOOT1 are mode pins brought to the header. A4/A5 double as the I2C bus (SDA/SCL) per the tech specs. · 来源: Arduino Nano ESP32 docs

JP2 (digital-side 1x15 header) 触点表

Same provenance as JP1. D11/D12/D10 carry the SPI bus in CIPO/COPI/CS wording (the datasheet uses the new SPI signal names); D0/D1 are the serial RX/TX pair. RST is wired to the reset button (PB1). · 来源: Arduino Nano ESP32 docs
