Dindex.rst6 ESP-WROVER-KIT is an ESP32-based development board produced by `Espressif <https://www.espressif.co…
8 ESP-WROVER-KIT features the following integrated components:
10 - ESP32-WROVER-E module
11 - LCD screen
12 - MicroSD card slot
14 Its another distinguishing feature is the embedded FTDI FT2232HL chip - an advanced multi-interface
16 without a separate JTAG debugger. ESP-WROVER-KIT makes development convenient, easy, and
17 cost-effective.
26 For more information, check `ESP32-WROVER-E Datasheet`_ and `ESP32 Datasheet`_.
31 The block diagram below shows the main components of ESP-WROVER-KIT and their interconnections.
