|
||||
What You Need
|
||||
-------------
|
||||
|
||||
* 1 × :ref:`ESP-WROVER-KIT V3 board <get-started-esp-wrover-kit-v3-board-front>`
|
||||
* 1 x Micro USB 2.0 Cable, Type A to Micro B

Overview
|
||||
--------
|
||||
|
||||
The ESP-WROVER-KIT is a development board built around the ESP32 and produced by `Espressif <https://espressif.com>`_. This board is compatible with multiple ESP32 modules, including the ESP32-WROOM-32 and ESP32-WROVER. The ESP-WROVER-KIT features support for an LCD and MicroSD card. The I/O pins have been broken out from the ESP32 module for easy extension. The board carries an advanced multi-protocol USB bridge (the FTDI FT2232HL), enabling developers to use JTAG directly to debug the ESP32 through the USB interface. The development board makes secondary development easy and cost-effective.
|
||||
|
||||
.. note::
|
||||
|
||||
ESP-WROVER-KIT V3 integrates the ESP32-WROVER module by default.
|
||||

Functional Description
|
||||
----------------------
|
||||
|
||||
The following lists and figures describe the key components, interfaces, and controls of ESP-WROVER-KIT board.
|
||||
|
||||
32.768 kHz
|
||||
An external precision 32.768 kHz crystal oscillator provides a low-power consumption clock used during Deep-Sleep mode.
|
||||
0R
|
||||
A zero Ohm resistor intended as a placeholder for a current shunt. May be desoldered or replaced with a current shunt to facilitate measurement of current required by ESP32 module depending on power mode.
|
||||
ESP32 Module
|
||||
ESP-WROVER-KIT is compatible with both the ESP32-WROOM-32 and the ESP32-WROVER. The ESP32-WROVER module features all the functions of ESP32-WROOM-32 and integrates an external 32-Mbit PSRAM for flexible extended storage and data processing capabilities.
|
||||
|
||||
.. note::
|
||||
|
||||
GPIO16 and GPIO17 are used as the CS and clock signal for PSRAM. To ensure reliable performance, the two GPIOs are not broken out.
|
||||
|
||||
FT2232
|
||||
The FT2232 chip is a multi-protocol USB-to-serial bridge. Users can control and program the FT2232 chip through the USB interface to establish communication with ESP32. The FT2232 chip also features USB-to-JTAG interface. USB-to-JTAG is available on channel A of the FT2232, whilst USB-to-serial is on channel B. The embedded FT2232 chip is one of the distinguishing features of the ESP-WROVER-KIT. It enhances users’ convenience in terms of application development and debugging. In addition, users need not purchase a JTAG debugger separately, which reduces the development cost, see `ESP-WROVER-KIT V3 schematic`_.
|
||||
UART
|
||||
Serial port: the serial TX/RX signals on the FT2232HL and the ESP32 are broken out to each side of JP11. By default, the two signals are connected with jumpers. To use the ESP32 module serial interface only, the jumpers may be removed and the module can be connected to another external serial device.
|
||||
SPI
|
||||
The SPI interface is used by the ESP32 to access flash and PSRAM memories within the module itself. To interface with another SPI device, an extra CS signal is needed. Please note that the voltage level on this interface depends on the module used (e.g 1.8V and 3.3V for the ESP32-WROVER and ESP32-WROOM-32 respectively).
|
||||
CTS/RTS
|
||||
Serial port flow control signals: the pins are not connected to the circuitry by default. To enable them, respective pins of JP14 must be shorted with jumpers.
|
||||
JTAG
|
||||
JTAG interface: the JTAG signals on FT2232HL and ESP32 are broken out to the two sides of JP8. By default, the two signals are disconnected. To enable JTAG, shorting jumpers are required on the signals.
|
||||
EN
|
||||
Reset button: pressing this button resets the system.
|
||||
Boot
|
||||
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.
|
||||
USB
|
||||
USB interface. It functions as the power supply for the board and the communication interface between PC and ESP32 module.
|
||||
Power Select
|
||||
Power supply selection interface: the ESP-WROVER-KIT can be powered through the USB interface or the 5V Input interface. The user can select the power supply with a jumper. More details can be found in section :ref:`get-started-esp-wrover-kit-v3-setup-options`, jumper header JP7.
|
||||
Power Key
|
||||
Power on/off button: toggling to the right powers the board on; toggling to the left powers the board off.
|
||||
5V Input
|
||||
The 5V power supply interface is used as a backup power supply in case of full-load operation.
|
||||
LDO
|
||||
NCP1117(1A). 5V-to-3.3V LDO. (There is an alternative pin-compatible LDO — LM317DCY, with an output current of up to 1.5A). NCP1117 can provide a maximum current of 1A. The LDO solutions are available with both fixed output voltage and variable output voltage. For details please refer to `ESP-WROVER-KIT V3 schematic`_.
|
||||
Camera
|
||||
Camera interface: a standard OV7670 camera module is supported.
|
||||
RGB
|
||||
Red, green and blue (RGB) light emitting diodes (LEDs), which may be controlled by pulse width modulation (PWM).
|
||||
I/O
|
||||
All the pins on the ESP32 module are led out to the pin headers on the ESP-WROVER-KIT. Users can program ESP32 to enable multiple functions such as PWM, ADC, DAC, I2C, I2S, SPI, etc.
|
||||
Micro SD Card
|
||||
Develop applications that access Micro SD card for data storage and retrieval.
|
||||
LCD
|
||||
ESP-WROVER-KIT supports mounting and interfacing a 3.2” SPI (standard 4-wire Serial Peripheral Interface) LCD, as shown on figure :ref:`get-started-esp-wrover-kit-v3-board-back`.

Allocation of ESP32 Pins
|
||||
------------------------
|
||||
|
||||
Several pins / terminals of ESP32 module are allocated to the on board hardware. Some of them, like GPIO0 or GPIO2, have multiple functions. If certain hardware is not installed, e.g. nothing is plugged in to the Camera / JP4 header, then selected GPIOs may be used for other purposes.
|
||||
|
||||
|
||||

.. note::
|
||||
|

The module's flash bus is connected to the pin header JP13 through 0-Ohm resistors R140 ~ R145. If the flash frequency needs to operate at 80 MHz for reasons such as improving the integrity of bus signals, it is recommended that resistors R140 ~ R145 be desoldered. At this point, the module's flash bus is disconnected with the pin header JP13.

ESP-WROVER-KIT V3
|
||||
=================
|
||||
|
||||
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.

WROOM, SOLO and WROVER Modules
|
||||
==============================
|
||||
|
||||
A family of small modules that contain ESP32 chip on board together with some key components including a crystal oscillator and an antenna matching circuit. This makes it easier to provide an ESP32 based solution ready to integrate into final products. Such modules can be also used for evaluation after adding a few extra components like a programming interface, bootstrapping resistors and break out headers. The key characteristics of these modules are summarized in the following table. Some additional details are covered in the following chapters.

As all previous version 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 version of ESP-WROVER-KIT board has ESP-WROVER-B module installed that integrates 64-MBit PSRAM for flexible extended storage and data processing capabilities. The board can accommodate other versions of ESP modules described under :ref:`esp-wroom-solo-wrover-modules`.
|
||||
|
||||
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.
|
||||
Comparing to :ref:`esp-modules-and-boards-esp-wrover-kit-v3`, this board has the following design changes:
|
||||
|
