6 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.

64 | FT2232 | The FT2232 chip serves as a multi-protocol USB-to-serial bridge |
66 | | communication with ESP32. FT2232 also features USB-to-JTAG |
67 | | interface which is available on channel A of the chip, while USB-to- |
68 | | serial is on channel B. The FT2232 chip enhances user-friendliness in |
