What You Need

• 1 × ESP-WROVER-KIT V3 board
• 1 × Micro USB 2.0 Cable, Type A to Micro B
• 1 × PC running Windows, Linux, or Mac OS

Overview

The ESP-WROVER-KIT is a development board produced by Espressif built around the 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.

Note

ESP-WROVER-KIT V3 integrates the ESP32-WROVER module by default.

Functional Description

The following list and figures describe the key components, interfaces, and controls of the ESP-WROVER-KIT board.

32.768 kHzAn external precision 32.768 kHz crystal oscillator provides the chip with a clock for low-power consumption during Deep-sleep mode.0RA zero Ohm resistor intended as a placeholder for a current shunt. It may be desoldered or replaced with a current shunt to facilitate measurement of the current required by the ESP32 module depending on the power mode.ESP32 Module

The ESP-WROVER-KIT is compatible with both the ESP-WROOM-32 and ESP32-WROVER. The ESP32-WROVER module features all the functions of the ESP-WROOM-32 and integrates an external 32-MBit PSRAM for flexible extended storage and data processing capabilities.

Note

GPIO16 and GPIO17 are used as the CS and clock signal for PSRAM. To ensure reliable performance, these two GPIOs are not broken out.
