Overview
1 Overview
ESP32-WROVER-E and ESP32-WROVER-IE are two powerful, generic Wi-Fi + Bluetooth + Bluetooth LE MCU
modules that target a wide variety of applications, ranging from low-power sensor networks to the most
demanding tasks, such as voice encoding, music streaming and MP3 decoding.
ESP32-WROVER-E comes with a PCB antenna, and ESP32-WROVER-IE with a connector for an external
antenna. The information in this datasheet is applicable to both modules.
The Series Comparison for the two modules is as follows:

This module uses PSRAM integrated in the chip’s package.
The integrated flash supports:
- More than 100,000 program/erase cycles
- More than 20 years data retention time
At the core of the module is the ESP32-D0WD-V3 chip or ESP32-D0WDR2-V3 chip*. The chip embedded is
designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the CPU
clock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a low-power coprocessor that can be
used instead of the CPU to save power while performing tasks that do not require much computing power, such
as monitoring of peripherals. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors,
SD card interface, Ethernet, high-speed SPI, UART, I2S, and I2C.
