ESP32-WROVER-E is a powerful, generic Wi-Fi + Bluetooth + Bluetooth LE MCU module that targets 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.

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 CPUclock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a low-power coprocessor that can beused instead of the CPU to save power while performing tasks that do not require much computing power, suchas 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.

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 A, making it suitable forbattery 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.
