1 Overview
ESP32-WROVER-E and ESP32-WROVER-IE are two powerful, generic WiFi-BT-BLE 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 an IPEX antenna. They both
feature a 4 MB external SPI flash and an additional 8 MB SPI Pseudo static RAM (PSRAM). The information in
this datasheet is applicable to both modules.
The ordering information of the two modules is listed as follows:

Notes:
1. The module with 8 MB flash or 16 MB flash is available for custom order.
2. For detailed ordering information, please see Espressif Product Ordering Information.
3. For dimensions of the IPEX connector, please see Chapter 11.
At the core of the module is the ESP32-D0WD-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 co-processor 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, Hall sensors, SD
card interface, Ethernet, high-speed SPI, UART, I²S and I²C.
Note:
* For details on the part numbers of the ESP32 family of chips, please refer to the document ESP32 Datasheet.
The integration of Bluetooth
®
, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted,
and that the module is all-around: using Wi-Fi allows a large physical range and direct connection to the Internet
through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast
low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for
battery powered and wearable electronics applications. The module supports a data rate of up to 150 Mbps,
and 20 dBm output power at the antenna to ensure the widest physical range. As such the module does offer
industry-leading specifications and the best performance for electronic integration, range, power consumption,
and connectivity.
The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as
well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that users can upgrade their products
even after their release, at minimum cost and effort.
Table 2 provides the specifications of the two modules.
