Overview of ESP-WROVER-KIT
The ESP-WROVER-KIT is a newly-launched development board 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 led 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.

The kit can be powered by either the microUSB port or the external DC power jack. The desired power source must be selected by shorting the proper jumper (shown in the following images). The FT2323 chip will appear as 2 separate serial interfaces when the board is plugged in to your computer. Only one will be usable as the UART for programming the ESP32 on board. When using the IO extender ports, make sure to return the IO signal to ground by using the nearest available ground pin.
To use a feature, be it the in-built LDO, the UART for programming or even the JTAG interface, they must be enabled by shorting the required jumpers. None is enabled by default without using jumpers. The EN and IO0 lines on the board are automatically controlled and thus there is no need to set the board to boot mode before using the flashing tool. However, the board may need to be reset by using the EN button after programming.
