ESP32-WROVER-B

Espressif System ESP32-WROVER-B Wireless Module Espressif ESP32-WROVER-B Wireless Module is a powerful and versatile wireless-bt-ble microcontroller Single chip module for a variety of applications.These applications range from low-power sensor networks to the most demanding tasks such as speech coding, music streaming and MP3 decoding. There are two variants of this module. One with a PCB antenna and the other with an IPEX antenna.The ESP32-WROVER-B features a 4MB external SPI flash and an additional 8MB SPI pseudo-static RAM (PSRAM). The core of the module is the ESP32-D0WD chip. The design of the embedded chip is scalable and adaptable.

There are two CPU cores that can be individually controlled, and the CPU clock frequency can be adjusted from 80MHz to 240MHz. 

Users can also turn off the CPU and use low-power co-processors to constantly monitor changes in peripherals or threshold crossings. 

ESP32 integrates a wide range of peripherals including capacitive touch sensors, Hall sensors, SD card interfaces, Ethernet, high speed SPI, UART, I2S and I2C
