ESP32 Modules and Boards
|

========================
|
||||
************************
|
||||
|
||||
Espressif designed and manufactured several development modules and boards to help users evaluate functionality of the ESP32 family of chips. Development boards, depending on intended functionality, have exposed GPIO pins headers, provide USB programming interface, JTAG interface as well as peripherals like touch pads, LCD screen, SD card slot, camera module header, etc.

WROOM 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.

Both modules have ESP32-D0WD chip on board of a smaller footprint than ESP32-D0WDQ6 installed in :ref:`ESP-WROOM-32 <esp-modules-and-boards-esp-wroom-32>`. Version "D" has a MIFA antenna. Version "U" has just an U.FL / IPEX antenna connector. That makes it 6.3 mm shorter comparing to "D", and also the smallest representative of the whole WROOM / WROVER family of modules.

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 chip that integrates 4MB 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.

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 version of ESP-WROVER-KIT boards, it is ready to accommodate an :ref:`esp-modules-and-boards-esp-wroom-32` or :ref:`esp-modules-and-boards-esp32-wrover` module.
|
||||
|
||||
This is the first release of ESP-WROVER-KIT shipped with 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.
