ESP32 WiFi-BT-BLE MCU Module / ESP-WROOM-32

ESP-WROOM-32 is a powerful, generic WiFi-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 chip, which is designed to be scalable and adaptive. There are 2 CPU cores

that can be individually controlled or powered, and the 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 coprocessor 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, low noise sense amplifiers, SD card interface, Ethernet, high speed SDIO/SPI, UART, I2S

and I2C.

The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted,

and that it is future proof: 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 for battery

powered and wearable electronics applications. ESP-WROOM-32 supports data rates up to 150 Mbps, and 22

dBm output power at the PA to ensure the widest physical range. As such the chip does offer industry leading

specifications and the best optimized performance for electronic integration, range and power consumption, and

connectivity.

The operating system is freeRTOS with LWIP;
