ESP32-PICO-DevKitM-2
********************
:link_to_translation:`zh_CN:[中文]`
Overview
========
ESP32-PICO-DevKitM-2 is an ESP32-based development board produced by `Espressif <https://espressif.com>`_.
The core of this board is `ESP32-PICO-MINI-02/02U <https://www.espressif.com/en/products/modules>`_ module with complete Wi-Fi and Bluetooth® functionalities. The development board features a USB-to-UART Bridge circuit which allows developers to connect the board to a computer's USB port for flashing and debugging.
All the IO signals and system power on ESP32-PICO-MINI-02/02U are led out to two rows of 18 x 0.1" header pads on both sides of the development board for easy access. For compatibility with Dupont wires, all header pads are populated with two rows of male pin headers.

To use ESP32's serial interface, remove the jumpers and connect another external serial device to the respective pins.
* - SPI
- By default, ESP32 uses its SPI interface to access flash and PSRAM memory inside the module. Use these pins to connect ESP32 to another SPI device. In this case, an extra chip select (CS) signal is needed. Please note that the interface voltage for the version with ESP32-WROVER is 1.8V, while that for the version with ESP32-WROOM-32 is 3.3 V.
* - JTAG
- JTAG interface. JTAG signals of FT2232 and ESP32 are broken out to the inward and outward sides of JP8 respectively. By default, these pairs of pins are disconnected. To enable JTAG, short the respective pins with jumpers as shown in Section `Setup Options`_.
* - FT2232
- The FT2232 chip serves as a multi-protocol USB-to-serial bridge which can be programmed and controlled via USB to provide communication with ESP32. FT2232 features USB-to-UART and USB-to-JTAG functionalities.

Setup Options
-------------
There are five jumper blocks available to set up the board functionality. The most frequently required options are listed in the table below.
======= ================ =========================================================
Header Jumper Setting Description of Functionality

JP7 |jp7-ext_5v| Power ESP-WROVER-KIT via an external power supply
JP7 |jp7-usb_5v| Power ESP-WROVER-KIT via USB

JP14 |jp14| Enable RTS/CTS flow control for serial communication
======= ================ =========================================================
Allocation of ESP32 Pins
------------------------
Some pins/terminals of ESP32 are allocated for use with the onboard or external hardware. If that hardware is not used, e.g., nothing is plugged into the Camera (JP4) header, then these GPIOs can be used for other purposes.
Some of the pins, such as GPIO0 or GPIO2, have multiple functions and some of them are shared among onboard and external peripheral devices. Certain combinations of peripherals cannot work together. For example, it is not possible to do JTAG debugging of an application that is using SD card, because several pins are shared by JTAG and the SD card slot.
In other cases, peripherals can coexist under certain conditions. This is applicable to, for example, LCD screen and SD card that share only a single pin GPIO21. This pin is used to provide D/C (Data/Control) signal for the LCD as well as the CD (Card Detect) signal read from the SD card slot. If the card detect functionality is not essential, then it may be disabled by removing R167, so both LCD and SD may operate together.
For more details on which pins are shared among which peripherals, please refer to the table in the next section.
Main I/O Connector/JP1

The JP1 connector consists of 14x2 male pins whose functions are shown in the middle two "I/O" columns of the table below. The two "Shared With" columns on both sides describe where else on the board a certain GPIO is used.

ESP-WROVER-KIT V4.1 Getting Started Guide
=========================================
:link_to_translation:`zh_CN:[中文]`
This guide shows how to get started with the ESP-WROVER-KIT V4.1 development board and also provides information about its functionality and configuration options.
What You Need
-------------
* :ref:`ESP-WROVER-KIT V4.1 board <get-started-esp-wrover-kit-v4.1-board-front>`
* USB 2.0 cable (A to Micro-B)
* Computer running Windows, Linux, or macOS
You can skip the introduction sections and go directly to Section `Start Application Development`_.
Overview
--------
ESP-WROVER-KIT is an ESP32-based development board produced by `Espressif <https://espressif.com>`_.
ESP-WROVER-KIT features the following integrated components:
- ESP32-WROVER-E module
- LCD screen
- microSD card slot
Another distinguishing feature is the embedded FTDI FT2232HL chip, an advanced multi-interface USB bridge. This chip enables to use JTAG for direct debugging of ESP32 through the USB interface without a separate JTAG debugger. ESP-WROVER-KIT makes development convenient, easy, and cost-effective.
Most of the ESP32 I/O pins are broken out to the board's pin headers for easy access.
.. note::
ESP32's GPIO16 and GPIO17 are used as chip select and clock signals for PSRAM. By default, the two GPIOs are not broken out to the board's pin headers in order to ensure reliable performance.

* - FT2232HL
- The FT2232HL chip serves as a multi-protocol USB-to-serial bridge which can be programmed and controlled via USB to provide communication with ESP32. FT2232HL also features USB-to-JTAG interface which is available on channel A of the chip, while USB-to-serial is on channel B. The FT2232HL chip enhances user-friendliness in terms of application development and debugging. See `ESP-WROVER-KIT V4.1 schematic`_.
* - 32.768 kHz
- External precision 32.768 kHz crystal oscillator serves as a clock with low-power consumption while the chip is in Deep-sleep mode.
* - 0R
- Zero-ohm resistor intended as a placeholder for a current shunt, can be desoldered or replaced with a current shunt to facilitate the measurement of ESP32's current consumption in different modes.
* - ESP32-WROVER-E module
- This ESP32 module features 64-Mbit PSRAM for flexible extended storage and data processing capabilities.
* - Diagnostic LEDs
- Four red LEDs connected to the GPIO pins of FT2232HL. Intended for future use.

To use ESP32's serial interface, remove the jumpers and connect another external serial device to the respective pins.
* - SPI
- By default, ESP32 uses its SPI interface to access flash and PSRAM memory inside the module. Use these pins to connect ESP32 to another SPI device. In this case, an extra chip select (CS) signal is needed. Please note that the voltage of this interface is 3.3 V.
* - CTS/RTS
- Serial port flow control signals: the pins are not connected to the circuitry by default. To enable them, short the respective pins of JP14 with jumpers.
* - JTAG
- JTAG interface. JTAG signals of FT2232HL and ESP32 are broken out to the inward and outward sides of JP2 respectively. By default, these pairs of pins are disconnected. To enable JTAG, short the respective pins with jumpers as shown in Section `Setup Options`_.
* - USB Port
- USB interface. Power supply for the board as well as the communication interface between a computer and the board.
* - EN Button
- Reset button.
* - BOOT Button
- Download button. Holding down **Boot** and then pressing **EN** initiates Firmware Download mode for downloading firmware through the serial port.
* - Power Switch
- Power On/Off Switch. Toggling toward the **Boot** button powers the board on, toggling away from **Boot** powers the board off.
* - Power Selector
- Power supply selector interface. The board can be powered either via USB or via the 5V Input interface. Select the power source with a jumper. For more details, see Section `Setup Options`_, jumper header JP7.
* - 5V Input
- 5V power supply interface for a standard coaxial power connector, 5.5 x 2.1 mm, center positive. This interface can be more convenient when the board is operating autonomously (not connected to a computer).
* - 5V Power On LED
- This red LED turns on when power is supplied to the board, either from **USB** or **5V Input**.
* - LDO
- NCP1117(1A). 5V-to-3.3V LDO. NCP1117 can provide a maximum current of 1A. The LDO on the board has a fixed output voltage, but the user can install an LDO with adjustable output voltage. For details, please refer to `ESP-WROVER-KIT V4.1 schematic`_.
* - Camera Connector
- Camera interface, a standard OV7670 camera module.
* - RGB LED
- Red, green and blue (RGB) light emitting diodes (LEDs), can be controlled by pulse width modulation (PWM).
* - I/O Connector
- All the pins on the ESP32 module are broken out to pin headers. You can program ESP32 to enable multiple functions, such as PWM, ADC, DAC, I2C, I2S, SPI, etc.
* - microSD Card Slot
- Useful for developing applications that access microSD card for data storage and retrieval.
* - LCD
- Support for mounting and interfacing a 3.2” SPI (standard 4-wire Serial Peripheral Interface) LCD, as shown in figure :ref:`get-started-esp-wrover-kit-v4.1-board-back`.

===========================================
:link_to_translation:`en:[English]`
本指南介绍了如何开始使用 ESP-WROVER-KIT V2 开发板及其功能和相关配置。有关 ESP-WROVER-KIT 其他版本的介绍，请见 :doc:`../../hw-reference/index`。
准备工作
-------------
* ESP-WROVER-KIT V2 开发板
* USB 数据线（A 转 Micro-B）
* PC（Windows、Linux 或 macOS）
你可以跳过介绍部分，直接前往 `应用程序开发`_ 章节。
概述
--------
ESP-WROVER-KIT 是 `乐鑫 <https://espressif.com>`_ 一款基于 ESP32 的开发板，集成了 LCD 屏幕和 microSD 卡槽。
ESP-WROVER-KIT 可选贴以下 ESP32 模组：
- ESP32-WROOM-32
- ESP32-WROVER 系列模组
此外，ESP-WROVER-KIT 的独特之处在于集成了一款先进多协议 USB 桥接器 (FTDI FT2232HL)，允许开发人员直接通过 USB 接口，使用 JTAG 对 ESP32 进行调试，无需额外的 JTAG 调试器。ESP-WROVER-KIT 可为开发人员提供简单、便捷且极具成本效益的开发体验。
为了便于使用，板上模组的绝大部分管脚均已引出至开发板的引脚。
.. note::
ESP-WROVER-KIT V2 板载 ESP32-WROVER 模组的 GPIO16 和 GPIO17 管脚用作 PSRAM 的片选和时钟信号。默认情况下，为了给用户提供可靠的性能，这两个 GPIO 管脚不引出至开发板引脚。

ESP32 管脚分配
------------------------
ESP32 模组的部分管脚/终端已被板上组件占用或用于外部硬件设备。如果某管脚对应的特定硬件未连接，则该管脚可用作他用。比如，摄像头/JP4 排针未连接相应硬件，则这些 GPIO 可用于其他用途。
部分管脚具备多个功能，可供板上组件或外部硬件设备同时使用，比如 GPIO0 和 GPIO2。由于管脚限制，一些外围设备不可同时使用，比如，由于 JTAG 和 SD 卡槽需共用部分管脚，因此一些使用 SD 卡功能的应用无法同时进行 JTAG 调试。
其他情况下，不同外设可同时使用。比如，LCD 屏幕和 SD 卡仅共用一个 GPIO21 管脚，可以同时使用。该管脚可为 LCD 屏幕提供 D/C（数据/控制）信号，并用于读取来自 SD 卡槽的 CD 信号（卡检测信号）。如无需使用卡检测功能，开发人员还可以通过移除 R167 来禁用该功能。此时，LCD 和 SD 卡槽可同时使用。
更多外设共享管脚的介绍，请见下一章节中的表格。

概述
--------
ESP-WROVER-KIT 是 `乐鑫 <https://espressif.com>`_ 一款基于 ESP32 的开发板。
ESP-WROVER-KIT 开发板已集成了如下组件：
- ESP32-WROVER-E 模组
- LCD 屏
- microSD 卡槽
此外，ESP-WROVER-KIT 的独特之处在于集成了一款先进多协议 USB 桥接器 (FTDI FT2232HL)，允许开发人员直接通过 USB 接口，使用 JTAG 对 ESP32 进行调试，无需额外的 JTAG 调试器。ESP-WROVER-KIT 可为开发人员提供简单、便捷且极具成本效益的开发体验。
为了便于使用，板上模组的绝大部分管脚均已引出至开发板的引脚。
.. note::
ESP32 的 GPIO16 和 GPIO17 管脚用作 PSRAM 的片选和时钟信号。默认情况下，为了给用户提供可靠的性能，这两个 GPIO 管脚不引出至开发板引脚。

- 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
- 电源开关。拨向 **Boot** 按键一侧，开发板上电；拨离 **Boot** 按键一侧，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 输入接口供电。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 `设置选项`_ 中有关 JP7 连接器的描述。
* - 5V Input
- 5V 电源接口。为标准同轴电源接口，5.5 x 2.1 mm，中心正极。建议仅在开发板自动运行（未连接 PC）时使用。
* - 5V Power On LED
- 当开发板通电后（USB 或外部 5V 供电），该红色指示灯将亮起。
* - LDO
- 5V-to-3.3V 低压差线型稳压器 NCP1117(1A)。NCP1117 最大电流输出为 1 A。板上 LDO 为固定输出电压，但用户也可以选用具有可变输出电压的 LDO。更多信息，请见 `ESP-WROVER-KIT V4.1 原理图`_。
* - 摄像头连接器

ESP32 管脚分配
------------------------
ESP32 模组的部分管脚或终端已被板上组件占用或用于外部硬件设备。如果某管脚对应的特定硬件未连接，则该管脚可用作他用。比如，摄像头/JP4 排针未连接相应硬件，则这些 GPIO 可用于其他用途。
部分管脚具备多个功能，可供板上组件或外部硬件设备同时使用，比如 GPIO0 和 GPIO2。由于管脚限制，一些外围设备不可同时使用，比如，由于 JTAG 和 SD 卡槽需共用部分管脚，因此一些使用 SD 卡功能的应用无法同时进行 JTAG 调试。
其他情况下，不同外设可同时使用。比如，LCD 屏幕和 SD 卡仅共用一个 GPIO21 管脚，可以同时使用。该管脚可为 LCD 屏幕提供 D/C（数据/控制）信号，并用于读取来自 SD 卡槽的卡检测信号。如无需使用卡检测功能，开发人员还可以通过移除 R167 来禁用该功能。此时，LCD 和 SD 卡槽可同时使用。
更多外设共享管脚的介绍，请见下一章节中的表格。
