ESP32-DevKitM-1
===============
:link_to_translation:`zh_CN:[中文]`
This user guide will help you get started with ESP32-DevKitM-1 and will also provide more in-depth information.
ESP32-DevKitM-1 is an ESP32-MINI-1/1U-based development board produced by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Users can either connect peripherals with jumper wires or mount ESP32-DevKitM-1 on a breadboard.

Start Application Development
-----------------------------
Before powering up your ESP32-DevKitM-1, please make sure that it is in good condition with no obvious signs of damage.
Required Hardware
^^^^^^^^^^^^^^^^^
- ESP32-DevKitM-1
- USB 2.0 cable (Standard-A to Micro-B)
- Computer running Windows, Linux, or macOS
Software Setup
^^^^^^^^^^^^^^
Please proceed to :doc:`../../get-started/index`, where Section :ref:`get-started-step-by-step` will quickly help you set up the development environment and then flash an application example onto your ESP32-DevKitM-1.
.. attention::
ESP32-DevKitM-1 boards manufactured before December 2, 2021 have a single core module installed. To verify what module you have, please check module marking information in `PCN-2021-021 <https://www.espressif.com/sites/default/files/pcn_downloads/PCN-2021-021%20ESP32-U4WDH%20%E5%8D%87%E7%BA%A7%E4%B8%BA%E5%8F%8C%E6%A0%B8%E5%A4%84%E7%90%86%E5%99%A8%E4%BA%A7%E5%93%81.pdf>`_ . If your board has a single core module installed, please enable single core mode (:ref:`CONFIG_FREERTOS_UNICORE`) in :ref:`menuconfig <get-started-configure>` before flashing your applications.

Power Source Select
-------------------
There are three mutually exclusive ways to provide power to the board:
* Micro USB port, default power supply
* 5V and GND header pins
* 3V3 and GND header pins
.. warning::
- The power supply must be provided using **one and only one of the options above**, otherwise the board and/or the power supply source can be damaged.
- Power supply by micro USB port is recommended.

- PC（Windows、Linux 或 macS）
软件设置
^^^^^^^^^^^
现在，请前往 :doc:`../../get-started/index` 中的 :ref:`get-started-step-by-step` 章节，查看如何设置开发环境，并尝试将示例项目烧录至你的开发板。
.. attention::
对于 2021 年 12 月 2 日之前生产的 ESP32-DevKitM-1，其搭载的模组为单核 MCU 模组。请查看 `PCN-2021-021 <https://www.espressif.com/sites/default/files/pcn_downloads/PCN-2021-021%20ESP32-U4WDH%20%E5%8D%87%E7%BA%A7%E4%B8%BA%E5%8F%8C%E6%A0%B8%E5%A4%84%E7%90%86%E5%99%A8%E4%BA%A7%E5%93%81.pdf>`_ 以确定开发板上搭载的模组是否为单核模组。对于搭载单核模组的开发板，烧录应用程序前，需要在 :ref:`menuconfig <get-started-configure>` 中启用单核模式 (:ref:`CONFIG_FREERTOS_UNICORE`)。

.. [1] P：电源；I：输入；O：输出。
.. [2] MTDI、GPIO0、GPIO2、MTDO 和 GPIO5 为 Strapping 管脚。在芯片上电和系统复位过程中，Strapping 管脚根据管脚的二进制电压值控制芯片功能。Strapping 管脚的具体描述和应用，请参考 `《ESP32 技术规格书》`_ > 章节 Strapping 管脚。
