ESP32-WROVER-B 64Mbits WIFI BT RF Transceiver Modules and Modems
Description
ESP32-WROVER-B Wireless Module is a powerful, generic WiFi-BT-BLE
MCU module that targets various applications. These applications
range from low-power sensor networks to the most demanding tasks,
such as voice encoding, music streaming, and MP3 decoding. This
module is provided in two variations. One module comes with a PCB
antenna and the other with an IPEX antenna. ESP32-WROVER-B features
a 4MB external SPI flash and an additional 8MB SPI Pseudo static
RAM (PSRAM).
At the core of the module is the ESP32-D0WD chip. The embedded chip
is designed to be scalable and adaptive. Two CPU cores can be
individually controlled, and the CPU clock frequency is adjustable
from 80MHz to 240MHz. The user may also power off the CPU and use
the low-power co-processor to monitor the peripherals for changes
or crossing of thresholds constantly. 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.
