ESP32-WROVER-KIT is so far the most sophisticated development board for the new ESP32 produced by Espressif.
The board has ESp32-WROOM32 module, LCD display connected to SPI port, micro SD card and USB-JTAG build in, but all JTAG signals are available on external connector too.
The power supply is jumper selectable and can be from 5V power adapter or USB via micro USB connector. Same USB is used for creating JTAG and COM port for data exchange.
We have very limited quantity from the first boards.

Minor note: It’s called “ESP-WROVER-KIT”, not “ESP32-WROVER-KIT” — http://espressif.com/en/products/hardware/esp-wrover-kit/overview — perhaps for future proofing for the kit itself for possible future non-ESP32 Espressif modules.

Don’t go too far with the asumptions about how they thought out the naming nicely – after all the kit contains the WROOM-32 module by default, so shouldn’t really be called a “WROVER” kit 😀
