1. To prevent the power-on state of the GPIO0 from being affected by the clock output on the PHY side, the RESET_N signal to PHY defaults to low, turning the clock output off. After power-on you can control RESET_N with GPIO5 to turn the clock output on. See also `RMII Clock Sourced Externally by PHY`_. For PHYs that cannot turn off the clock output through RESET_N, it is recommended to use a crystal module that can be disabled / enabled externally. Similarly like when using RESET_N, the oscillator module should be disabled by default and turned on by ESP32 after power-up. For a reference design please see `ESP32-Ethernet-Kit V1.1 Ethernet board (A) schematic`_.
|
||||
|
||||
|
||||
2. The ESP32 pins GPIO16 and GPIO17 are not broken out to the ESP32-WROVER-B module and therefore not available for use. If you need to use these pins, please solder a module without PSRAM memory inside, e.g. the ESP32-WROOM-32D or ESP32-SOLO-1.

Modules
|
||||
=======
|
||||
|
||||
This is a family of ESP32-based modules with some integrated key components, including a crystal oscillator and an antenna matching circuit. The modules constitute ready-made solutions for integration into final products. If combined with a few extra components, such as a programming interface, bootstrapping resistors, and pin headers, these modules can also be used for evaluation of ESP32's functionality.
|
||||
|
||||
The key characteristics of these modules are summarized in the table below. Some additional details are covered in the following sections.

ESP32-PICO-KIT V4
|
||||
-----------------
|
||||
|
||||
The smallest ESP32 development board with all the components required to connect it directly to a PC USB port, and pin headers to plug into a mini breadboard. It is equipped with ESP32-PICO-D4 module that integrates 4 MB flash memory, a crystal oscillator, filter capacitors and RF matching circuit in one single package. As result, the fully functional development board requires only a few external components that can easy fit on a 20 x 52 mm PCB including antenna, LDO, USB-UART bridge and two buttons to reset it and put into download mode.

-----------------
|
||||
|
||||
The first public release of Espressif's ESP32-PICO-D4 module on a mini development board. The board has a USB port for programming and debugging and two rows of 20 pin headers to plug into a breadboard. The ESP32-PICO-D4 module itself is small and requires only a few external components. Besides two core CPUs it integrates 4MB flash memory, a crystal oscillator and antenna matching components in one single 7 x 7 mm package. As a result the module and all the components making the complete development board fit into 20 x 52 mm PCB.

The ESP-WROVER-KIT V3 development board has dual port USB to serial converter for programming and JTAG interface for debugging. Power supply is provided by USB interface or from standard 5 mm power supply jack. Power supply selection is done with a jumper and may be put on/off with a separate switch. This board has MicroSD card slot, 3.2” SPI LCD screen and dedicated header to connect a camera. It provides RGB diode for diagnostics. Includes 32.768 kHz XTAL for internal RTC to operate it in low power modes.
|
||||
|
||||
As all previous versions of ESP-WROVER-KIT boards, it is ready to accommodate an :ref:`esp-modules-and-boards-esp32-wroom-32` or :ref:`esp-modules-and-boards-esp32-wrover` module.
|
||||
|
||||
This is the first release of ESP-WROVER-KIT shipped with :ref:`esp-modules-and-boards-esp32-wrover` module installed by default. This release also introduced several design changes to conditioning and interlocking of signals to the bootstrapping pins. Also, a zero Ohm resistor (R166) has been added between WROVER/WROOM module and VDD33 net, which can be desoldered, or replaced with a shunt resistor, for current measurement. This is intended to facilitate power consumption analysis in various operation modes of ESP32. Refer to schematic - the changes are enclosed in green border.

* 片外 RAM 与片外 flash 使用相同的 cache 区域，即频繁在片外 RAM 访问的变量可以像在片上 RAM 中一样快速读取和修改。但访问大块数据时（大于 32 KB），cache 空间可能会不足，访问速度将回落到片外 RAM 访问速度。此外，访问大块数据可以“挤出” flash cache，可能会降低代码执行速度。

--------
|
||||
|
||||
本节介绍用于 ESP32-Ethernet-Kit 开发板的硬件配置选项。
|
||||
|
||||
|
||||
功能选择开关
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
拨码开关打开时，拨码开关将列出的 GPIO 路由到 FT2232H 以提供JTAG功能。拨码开关关闭时，GPIO 可以用于其他目的。
|
||||

|
||||

|
||||
|
||||
.. note::
|
||||
|
||||
拨码开关旁边开发板的丝印层上的 GPIO 管脚标记的位置是不正确的。请以表格中的顺序为准。
|
||||
|
||||
|
||||
RMII 时钟源选择
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
RMII 工作模式下的以太网 MAC 和 PHY 需要一个公共的 50MHz 同步时钟（即 RMII 时钟），它既可以由外部提供，也可以由内部的 ESP32 APLL 产生。
|
||||
|
||||
.. note::
|
||||
|
||||
有关 RMII 时钟源选择的更多信息，请参见 `ESP32-Ethernet-Kit V1.1 以太网母板（A 板）原理图`_，第 2 页的位置 D2。
|
||||
|
||||
|
||||
PHY 侧提供 RMII 时钟
|
||||
"""""""""""""""""""""""""""""
|
||||
|
||||
ESP32-Ethernet-Kit 默认配置为 IP101GRI 的 50M_CLKO 信号线提供 RMII 时钟，该时钟信号由 PHY 外侧连接的 25MHz 无源晶振经过倍频产生。详情请参见下图。
|
||||
|
||||
.. figure:: ../../_static/esp32-ethernet-kit-rmii-clk-from-phy.png

|
||||
:figclass: align-center
|
||||
|
||||
PHY 侧提供 RMII 时钟
|
||||
|
||||
请注意，系统上电时 RESET_N 旁的下拉电阻会将 PHY 置于复位状态，ESP32 需要通过 GPIO5 将 RESET_N 拉高才能启动 PHY，只有这样才能保证系统的正常上电，否则 ESP32 会存在一定几率进入下载模式（当 REF_CLK_50M 时钟信号在 GPIO0 上电采样阶段刚好处于高电平）。
|
||||
|
||||
|
||||
ESP32 APLL 内部提供的 RMII 时钟
|
||||
""""""""""""""""""""""""""""""""""""
|
||||
|
||||
另一种选择是从 ESP32 APLL 内部获取 RMII 时钟，请参见下图。来自 GPIO0 的时钟信号首先被反相，以解决传输线延迟的问题，然后提供给 PHY。
|
||||
|
||||

ESP32 APLL 内部提供的 RMII 时钟
|
||||
|
||||
要实现此选项，用户需要在板子上移除或添加一些阻容元器件。有关详细信息，请参见 `ESP32-Ethernet-Kit V1.1 以太网母板（A 板）原理图`_，第 2 页，位置 D2。请注意，如果 APLL 已经用于其他用途（如 I2S 外设），那么只能使用外部 RMII 时钟。

1. 为防止 ESP32 侧 GPIO0 的上电状态受 PHY 侧时钟输出的影响，PHY 侧 RESET_N 默认为低，以关闭 PHY 侧时钟输出。上电后，您可通过 GPIO5 控制 RESET_N 以打开该时钟输出。参见 `PHY 侧提供 RMII 时钟`_。对于无法通过 RESET_N 关闭时钟输出的 PHY，PHY 侧建议使用可在外部禁用/使能的有源晶振。与使用 RESET_N 类似，默认情况下晶振模块应禁用，并在上电后由 ESP32 开启。有关参考设计，请参见 `ESP32-Ethernet-Kit V1.1 以太网母板（A 板）原理图`_。
|
||||
|
||||
|
||||
2. ESP32 芯片的 GPIO16 和 GPIO17 管脚没有引出至 ESP32-WROVER-B 模组的管脚，因此无法使用。如需使用 ESP32 的 GP1016 和 GPIO17 管脚，建议更换其他不含 PSRAM 的模组，比如 ESP32-WROOM-32D 或 ESP32-SOLO-1。
|
||||
|
||||
|
||||
应用程序开发
|
||||
-------------
|
||||
|
||||
ESP32-Ethernet-Kit 上电前，请首先确认开发板完好无损。
|
||||
|
||||
|
||||
初始设置
|
||||
^^^^^^^^^^
|
||||
|
||||
1. 首先，请将 :ref:`以太网母板（A 板）<get-started-esp32-ethernet-kit-a-v1.1-layout>` 上的所有开关均拨至 **ON** 状态，使 **功能选择开关** 处于默认状态。
|
||||
2. 为了方便应用程序的下载和测试，不要为开发板输入任何信号。
|
||||
3. 此时可以连接 `PoE 子板（B 板）`_ ，但不要向 B 板连接任何外部电源。
|
||||
4. 使用 USB 数据线将 :ref:`以太网母板（A 板）<get-started-esp32-ethernet-kit-a-v1.1-layout>` 连接至 PC。
|
||||
5. 将 **电源开关** 从 GND 拨至 5V0 一侧。此时，**5V Power On LED** 应点亮。
|
||||
|
||||
|
||||
正式开始开发
|
||||
^^^^^^^^^^^^^
|
||||
|
||||
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您的开发板。
|
||||
|
||||
请务必在进入下一步前，确保您已完成上述所有步骤。
|
||||
|
||||
|
||||
配置与加载以太网示例
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
在完成开发环境设置和开发板测试后，您可以配置并烧录 :example:`ethernet/ethernet` 示例。本示例专门用于测试以太网功能，支持不同 PHY，包括 :ref:`get-started-esp32-ethernet-kit-v1.1` 开发板使用的 **IP101GRI** 。
|
||||
|
||||
|
||||
针对 ESP32-Ethernet-Kit V1.0 的主要修改：
|
||||
-----------------------------------------
|
||||
|
||||
* 原 GPIO0 反相后时钟提供给 PHY 方案改为由 PHY 侧外接无源晶振，提供时钟给 GPIO0。原用于控制有源晶振的 OSC_EN 的 IO2 释放，可用作其他用途。
|
||||
* 为防止 ESP32 侧 GPIO0 的上电状态受到 PHY 侧时钟输出的影响，PHY 侧 RESET_N 默认为低，关闭 PHY 侧时钟输出。而后可通过 GPIO5 控制 RESET_N 打开该时钟输出。
|
||||
* 移除 FT2232H 芯片的外部 SPI Flash U6。
|
||||
* 移除流控的测试排针 J4。
|
||||
* 移除 nTRST JTAG信号，相应的 GPIO4 可用作其他用途。
|
||||
* GPIO15 线上的上拉电阻 R68 移至 JTAG 的 MTDO 侧。
|
||||
* 为了加强 A 板和 B 板连接间的防呆设计（减少反向插入 B 板的机会），将原先 A 板上的 2 排 4 针排针改为 1 排 4 针排母和 1 排 4 针排针。相应的 4 针排针排和排母排则安装在 B 板上。
|
||||
