ESP32-DevKitC V4 Getting Started Guide
======================================
+:link_to_translation:`zh_CN:[中文]`
This user guide shows how to get started with ESP32-DevKitC V4 development board. For description of other versions of the ESP32-DevKitC check :doc:`../hw-reference/index`.
ESP32-DevKitC V4 is a small-sized ESP32-based development board produced by `Espressif <https://espressif.com>`_. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can connect these pins to peripherals as needed. Standard headers also make development easy and convenient when using a breadboard.
-The board supports various ESP32 modules, including :ref:`esp-modules-and-boards-esp32-wroom-32`, :ref:`ESP32-WROOM-32U <esp-modules-and-boards-esp32-wroom-32d-and-u>`, :ref:`ESP32-WROOM-32D <esp-modules-and-boards-esp32-wroom-32d-and-u>` and :ref:`esp-modules-and-boards-esp32-solo-1`.

Functional Description
The following list and figure below describe key components, interfaces and controls of ESP32-DevKitC V4 board.
ESP32-WROOM-32
- :ref:`esp-modules-and-boards-esp32-wroom-32` module soldered to the ESP32-DevKitC V4 board. Optionally ESP32-WROOM-32D, ESP32-WROOM-32U or ESP32-SOLO-1 module may be soldered instead of the ESP32-WROOM-32.
-USB-UART Bridge
- A single chip USB-UART bridge provides up to 3 Mbps transfers rates.
-Boot
+ :ref:`esp-modules-and-boards-esp32-wroom-32` module soldered to the ESP32-DevKitC V4 board.
+Optional Space for ESP32-WROVER
+ Longer :ref:`esp-modules-and-boards-esp32-wrover` modules may be soldered instead of the ESP32-WROOM-32.
+USB-to-UART Bridge
+ A single chip USB-to-UART bridge provides up to 3 Mbps transfers rates.
+Boot Button
Download button: holding down the **Boot** button and pressing the **EN** button initiates the firmware download mode. Then user can download firmware through the serial port.
+EN Button
+ Reset button: pressing this button resets the system.
Micro USB Port
USB interface. It functions as the power supply for the board and the communication interface between PC and the ESP module.
5V Power On LED
This LED lights when the USB or an external 5V power supply is applied to the board. For details see schematic in `Related Documents`_.
-EN
- Reset button: pressing this button resets the system.
-I/O
+I/O Connector
Most of the pins on the ESP module are broken out to the pin headers on the board. Users can program ESP32 to enable multiple functions such as PWM, ADC, DAC, I2C, I2S, SPI, etc.

+
+功能描述
+--------------------
+
+ESP-WROVER-KIT 开发板的主要组件、接口及控制方式如下文所示。
+
+32.768 kHz 晶振
+ 32.768 kHz 晶振，可提供 Deep-sleep 下使用的低功耗时钟。
+USB-UART 桥接器
+ 单芯片 USB-UART 桥接器 (FT2232)，可提供高达 3 Mbps 的传输速率。开发者可通过 USB 接口对 FT2232 芯片进行控制和编程，与 ESP32 建立连接。FT2232 芯片可在通道 A 提供 USB-to-JTAG 接口功能，并在通道 B 提供 USB-to-serial 接口功能。ESP-WROVER-KIT 的内置 FT2232 芯片功能强大，是这款开发板的特色之一，可显著便利用户的应用开发与调试。此外，用户无需单独购买 JTAG 调试器，可降低应用开发成本。具体请见 `ESP-WROVER-KIT V4.1 原理图`_ 。
+
+0 欧电阻
+ ESP-WROVER-KIT 开发板设计了一个 0 欧电阻，可在测量 ESP32 系列模组在不同功耗模式下的电流时，直接移除或替换为分流器。
+
+ESP32-WROVER 模组
+ ESP-WROVER-KIT V4.1 默认贴 ESP-WROVER-B 模组，内置 8 MB PSRAM，可提供灵活的额外存储空间和数据处理能力。本开发板支持的其他模组的信息，请见 :ref:`esp-wroom-solo-wrover-modules`。
+
+ .. note::
+
+ GPIO16 和 GPIO17 用于为 PSRAM 提供 CS 和时钟信号，因此并未引出。
+
+诊断 LED 信号灯
+ 本开发板 FT2232 芯片的 GPIO 管脚连接了 4 个 LED 信号灯，以备后用。
+
+UART
+ FT2232HL 和 ESP32 的串行 TX/RX 信号已引出至 JP2 的两端。默认情况下，这两路信号由跳线帽连接。如果仅需使用 ESP32 模组串口，则可移除相关跳线帽，将模组连接至其他外部串口设备。
+
+SPI
+ 该 SPI 接口可用于 ESP32 访问模组 flash 和 PSRAM 内存。注意，该接口的电压取决于开发板上贴的模组。
+
+CTS/RTS
+ 串口流控信号。管脚默认不连接至电路。为了使能该功能，必须用跳线帽断路掉 JP14 连接器的相应管脚。
+
+JTAG
+ FT2232HL 和 ESP32 的串口 JTAG 信号已引出至 JP2 连接器的两端。默认情况下，这两路信号不连接。如需使能 JTAG，请按照 :ref:`设置选项 <get-started-esp-wrover-kit-setup-options>` 中的介绍，连接跳线帽。
+
+USB 端口
+ USB 端口，可用作电路板的供电电源或连接 PC 端的通信接口。
+
+EN 按键
+ 复位键，可重置系统。
+
+Boot 按键
+ 下载按键。按下 **Boot** 键并保持，同时按一下 **EN** 键（此时不要松开 **Boot** 键）进入固件下载模式，通过串口下载固件。
+
+电源开关
+ 拨置右侧，开发板上电；拨置左侧，开发板掉电。
+
+电源选择开关
+ ESP-WROVER-KIT 开发板可通过 USB 端口或 5V 输入端口供电。用户可使用跳线帽在两种供电模式中进行选择。更多详细信息，请见章节 :ref:`设置选项 <get-started-esp-wrover-kit-setup-options>` 中有关 JP7 连接器的描述。
+
+5V 输入
+ 5V 电源接口仅用于全负荷工作下的后备电源。
+
+5V LED 电源指示灯
+ 当开发板通电后（USB 或外部 5V 供电），该指示灯将亮起。
+LDO
+ 5V-to-3.3V LDO NCP1117(1 A)（也可选 Pin-to-Pin LDO LM317DCY，最高输出电流为 1.5 A）。NCP1117 最大电流输出为 1 A。LDO 解决方案同时支持固定输出电压和可变输出电压。更多信息，请见 `ESP-WROVER-KIT V4.1 原理图`_。
+
+摄像头连接器
+ 摄像头接口：支持标准 OV7670 摄像头模块。
+
+RGB LED
