{IDF_TARGET_NAME} 芯片具有 31 个物理 GPIO 管脚GPIO0 ~ GPIO30
每个管脚都可用作一个通用 IO或连接一个内部的外设 信号。通过 GPIO 交换矩阵和 IO MUX可配置外设模块的输入信号来源于任何的 IO 管脚,并且外设模块的输 出信号也可连接到任意 IO 管脚。这些模块共同组成了芯片的 IO 控制。更多详细信息,请参阅 *{IDF_TARGET_NAME} 技术参考手册* > *IO MUX GPIO 矩阵GPIO、IO_MUX* [`PDF <{IDF_TARGET_TRM_CN_URL}#iomuxgpio>`__]
下表提供了各管脚的详细信息,部分 GPIO 具有特殊的使用限制,具体可参考表中的注释列。

.. note::
- Strapping 管脚GPIO4、GPIO5、GPIO8、GPIO9 GPIO15 Strapping 管脚。更多信息请参考 `ESP32-C6 技术规格书 <{IDF_TARGET_DATASHEET_CN_URL}>`_。
- SPI0/1GPIO24-30 通常用于 SPI flash不推荐用于其他用途。
- USB-JTAGGPIO12 GPIO13 默认用于 USB-JTAG。用做 GPIO 时驱动程序将禁用 USB-JTAG。
- 对于内置 SiP flash 的芯片型号GPIO24 ~ GPIO30 专门用于连接 SiP flash; GPIO10 ~ GPIO11 未引出至芯片管脚。因此,对于这类芯片只有 22 GPIO 管脚可用。
- 对于无内置 SiP flash 的芯片型号,则 GPIO14 未引出至芯片管脚。
