The ESP32-WROOM-32E is a powerful, generic Wi-Fi+BT+BLE 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.
At the core of this module is the ESP32-D0WDQ6 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 user may also power off the CPU and make use of the low-power co-processor to
constantly monitor the peripherals for changes or crossing of thresholds. ESP32 integrates a rich set of peripherals,
ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I²S and
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,
The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as
