========
|
||||
|
||||
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.
|
||||
|
||||
.. note::
|
||||
|
||||
ESP32-PICO-DevKitM-2 comes with male headers by default.
|
||||
|
||||
ESP32-PICO-DevKitM-2 provides the users with hardware for development of applications based on the ESP32, making it easier for users to explore ESP32 functionalities.

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.

Since GPIO32 and GPIO33 are connected to the oscillator by default, they are not connected to the JP1 I/O connector to maintain signal integrity. This allocation may be changed from the oscillator to JP1 by desoldering the zero-ohm resistors from positions R11/R23 and re-soldering them to positions R12/R24.

|
||||
|
||||
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.
|
||||
|
||||
|
||||

|
||||
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.
|
||||
|
||||
|
||||

* - Key Component
|
||||
- Description
|
||||
* - 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.

||||
- Four red LEDs connected to the GPIO pins of FT2232HL. Intended for future use.
|
||||
* - UART
|
||||
- Serial port. The serial TX/RX signals of FT2232HL and ESP32 are broken out to the inward and outward sides of JP2 respectively. By default, these pairs of pins are connected with jumpers. 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.
|
||||

Allocation of ESP32 Pins
|
||||
------------------------
|
||||
|
||||
Some pins or 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 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.

|

|

.. note::
|
||||
|
||||
Since GPIO32 and GPIO33 are connected to the oscillator by default, they are not connected to the JP1 I/O connector to maintain signal integrity. This allocation may be changed from the oscillator to JP1 by desoldering the zero-ohm resistors from positions R11 or R23 and re-soldering them to positions R12 or R24.

SPI Flash pins are used to access the internal flash memory. Therefore, they are not available to connect external SPI devices. Those pins are exposed for monitoring or for advanced usage only.
|
||||
|
||||
.. important::
|
||||
|
||||
The module's flash bus is connected to the jumper block JP2 through zero-ohm resistors R140 ~ R145. If the flash memory needs to operate at the frequency of 80 MHz, for reasons such as improving the integrity of bus signals, you can desolder these resistors to disconnect the module's flash bus from the pin header JP2.

|
||||
- 可选贴 ESP32-WROOM-32 或 ESP32-WROVER。ESP32-WROVER 模组完整集成了 ESP32-WROOM-32 的所有功能，且内置 32-Mbit PSRAM，可提供灵活的额外存储空间和数据处理能力。
|
||||
* - 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，必须用跳线帽短路掉 JP14 的相应管脚。
|
||||
* - UART
|
||||
- 串口。FT2232HL 和 ESP32 的串行 TX/RX 信号已引出至 JP11 的两端。默认情况下，这两路信号由跳线帽连接。如果要跳过 FT2232 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
|
||||
- 默认情况下，ESP32 使用 SPI 接口访问内置 flash 和 PSRAM。使用这些引脚连接 ESP32 和其他 SPI 设备。这种情况下，需增加额外的片选 (CS) 信号。注意，选贴 ESP32-WROVER 模组时，该接口的工作电压为 1.8 V；选贴 ESP32-WROOM-32 时，该接口的工作电压为 3.3 V。
|
||||
* - JTAG
|
||||
- JTAG 接口。FT2232HL 和 ESP32 的 JTAG 信号已引出至 JP8 的两端。默认情况下，这两路信号不连接。如需使能 JTAG，请按照 `设置选项`_ 的介绍，连接跳线帽。
|
||||
* - FT2232
|
||||
- FT2232 多协议 USB 转串口桥接器。开发人员可通过 USB 接口对 FT2232 芯片进行控制和编程，与 ESP32 建立连接。FT2232 具有 USB-to-UART 和 USB-to-JTAG 功能。
|
||||
* - EN
|
||||
- 复位按键。
|
||||
* - Boot
|
||||

|
||||
* - USB
|
||||
- USB 接口。可用作开发板的供电电源，或连接 PC 和开发板的通信接口。
|
||||
* - 电源选择开关
|
||||
- ESP-WROVER-KIT 开发板可通过 USB 端口或 5 V 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。
|
||||
* - 电源开关
|
||||
- 拨向 **USB** 按键一侧，开发板上电；拨离 **USB** 按键一侧，开发板掉电。
|
||||
* - 5V Input
|
||||
- 5 V 电源接口建议仅在开发板自动运行（未连接 PC）时使用。仅用于全负荷工作下的后备电源。
|
||||
* - 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 V2 原理图`_。
|
||||
* - 摄像头
|
||||
- 摄像头接口，支持标准 OV7670 摄像头模块。
|
||||
* - RGB LED
|
||||
- 红绿蓝发光二极管，可由 PWM（脉冲宽度调制）控制。
|
||||
* - I/O
|
||||
- 板上模组的所有管脚均已引出至开发板的排针。用户可以对 ESP32 进行编程，实现 PWM、ADC、DAC、I2C、I2S、SPI 等多种功能。
|
||||
* - microSD 卡槽
|
||||
- microSD 卡槽，可扩充存储空间：当 ESP32 进入下载模式时，GPIO2 不可处于高电平。然而，为了使能 microSD 卡功能，需为 GPIO2 增加一个上拉电阻。默认情况下，GPIO2 和上拉电阻 R153 处于断开状态。为了使能 microSD 卡，请按照 `设置选项`_ 章节的要求，连接 JP1 连接器。
|
||||
* - LCD 显示屏
|
||||
- 支持贴装一款 3.2” 的 SPI（标准四线串行外设接口）LCD 显示器，请见 :ref:`get-started-esp-wrover-kit-v2-board-back`。

:header-rows: 1
|
||||
|
||||
* - 主要组件
|
||||
- 基本介绍
|
||||
* - 32.768 kHz
|
||||
- 外接 32.768 kHz 晶振，可提供 Deep-sleep 下使用的低功耗时钟。
|
||||
* - 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 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。

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。
|
||||
|
||||
