Espressif ESP32-WROVER-B Wireless Module is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications. These applications range from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming, and MP3 decoding. ESP32-WROVER-B features a 4MB external SPI flash and an additional 32MB SPI Pseudo static RAM (PSRAM).

The ESP32-WROVER-B MCU Modules use the ESP32-D0WD chip at its core. This SoC features two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80MHz to 240MHz. The 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.

ESP-32S Wifi Bluetooth combo module provides SDK Firmware for fast online programming and open source toolchains based on GCC for development support. It is designed for Generic low power IoT sensor hub, loggers, video streaming for the camera, Wi-Fi & Bluetooth enabled devices, Home automation, and mesh network applications, aimed at makers, hardware engineers, software engineers and solution provides.

ESP32 is a single chip 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra-low-power 40 nm technology. It is designed and optimized for the best power performance, RF performance, robustness, versatility, features, and reliability, for a wide variety of applications, and different power profiles.

ESP32 is the most integrated solution for Wi-Fi + Bluetooth applications in the industry with less than 10 external components. ESP32 integrates the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. As such, the entire solution occupies a minimal Printed Circuit Board (PCB) area.

ESP32 is designed for mobile, wearable electronics, and the Internet of Things (IoT) applications. It has many features of state-of-the-art low power chips, including fine resolution clock gating, power modes, and dynamic power scaling.
