Description:
This section describes several revisions of ESP-WROVER-KIT development board.
All versions of ESP-WROVER-KIT are ready to accommodate an ESP-WROOM-32 or ESP32-WROVER module.
ESP-WROVER-KIT 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. The 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
Built-in USB-JTAG Debugger
Bogged down in bugs? We have come up with a solution! ESP32 supports JTAG debugging, while the ESP-WROVER-KIT integrates a USB debugger, as well. This makes debugging and tracing complex applications very easy, without the need for any additional hardware.
Advanced Hardware
ESP32 is engineered to be fast, smart and versatile. The ESP-WROVER-KIT complements these characteristics by offering an on-board high-speed Micro-SD card interface, VGA camera interface, as well as a 3.2” SPI LCD panel and I/O expansion capabilities.
Wide Compatibility
Have you been developing your applications around the ESP-WROOM-32 module? Not only does the ESP-WROVER-KIT support the popular ESP-WROOM-32 module, but it also supports the new ESP32-WROVER module.
ESP-WROVER-KIT V1 / ESP32 DevKitJ V1
First version of ESP-WROVER-KIT. Shipped with ESP-WROOM-32 on board.

ESP-WROVER-KIT V2
This is updated version of ESP32 DevKitJ V1 described above with design improvements identified when DevKitJ was in use, e.g. improved support for SD card. By default board has ESP-WROOM-32 module installed.
Overview
The ESP-WROVER-KIT is a development board produced by Espressif built around ESP32. This board is compatible with ESP32 modules, including the ESP-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.

ESP-WROVER-KIT V3
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.
